Pisa (Italian pronunciation: [ˈpiːza] ) is a city in Tuscany, Central Italy, on the right bank of the mouth of the River Arno on the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its Leaning Tower (the bell tower of the city's cathedral), the city of over 88,332 residents (around 200,000 with the metropolitan area) contains more than 20 other historic churches, several palaces and various bridges across the River Arno. The city is also home of the University of Pisa, which has a history going back to the 12th century.
History
Ancient times
The origin of the name Pisa is a mystery. Pisa's origins remained unknown for centuries. The city lies at the junction of two rivers, the Arno and the Serchio in the Ligurian Sea forming a laguna area. The Pelasgi, the Greeks, the Etruscans and the Ligurians have variously been proposed as founders of the city. Archeological remains from the 5th century BC confirmed the existence of a city at the sea, trading with Greeks and Gauls. The presence of an Etruscan necropolis, discovered during excavations in the Arena Garibaldi in 1991, clarified its Etruscan origins.
Ancient Roman authors referred to Pisa as an old city. Servius wrote that the Teuti, or Pelopes, the king of the Pisei, founded the town thirteen centuries before the start of the common era. Strabo referred Pisa's origins to the mythical Nestor, king of Pylos, after the fall of Troy. Virgil in his Aeneid states that Pisa was already a great and developed centre by the times described; the foundation of the city in the 'Etruscan lands' has been credited to settlers from the Alpheus coast.

The maritime role of Pisa should have been already prominent if the ancient authorities ascribed to it the invention of the rostrum: it took advantage of being the only port along the western coast from Genoa (then a small village) to Ostia. Pisa served as a base for Roman naval expeditions against Ligurians, Gauls and Carthaginians. In 180 BC, it became a Roman colony under Roman law, as Portus Pisanus. In 89 BC, Portus Pisanus became a municipium. Emperor Augustus fortified the colony into an important port and changed the name in Colonia Iulia obsequens. From 313 it became the seat of a bishopric.
Late Antiquity and Early Middle Ages
During the later years of the Roman Empire, Pisa did not decline as much as the other cities of Italy, probably thanks to the complexity of its river system and its consequent ease of defence. In the 7th century Pisa helped Pope Gregory I by supplying numerous ships in his military expedition against the Byzantines of Ravenna: Pisa was the sole Byzantine centre of Tuscia to fall peacefully in Lombard hands, through assimilation with the neighbouring region where their trading interests were prevailing. Pisa began in this way its rise to the role of main port of the Upper Tyrrhenian Sea and became the main trading centre between Tuscany and Corsica, Sardinia and the southern coasts of France and Spain.

After Charlemagne had defeated the Lombards under the command of Desiderius in 774, Pisa went through a crisis but soon recovered. Politically it became part of the duchy of Lucca. In 930 Pisa became the county centre (status it maintained until the arrival of Otto I) within the mark of Tuscia. Lucca was the capital but Pisa was the most important city, as in the middle of 10th century Liutprand of Cremona, bishop of Cremona, called Pisa Tusciae provinciae caput ("capital of the province of Tuscia"), and one century later the marquis of Tuscia was commonly referred to as "marquis of Pisa". In 1003 Pisa was the protagonist of the first communal war in Italy, against Lucca of course. From the naval point of view, since the 9th century the emergence of the Saracen pirates urged the city to expand its fleet: in the following years this fleet gave the town an opportunity for more expansion. In 828 Pisan ships assaulted the coast of North Africa. In 871 they took part in the defence of Salerno from the Saracens. In 970 they gave also strong support to the Otto I's expedition, defeating a Byzantine fleet in front of Calabrese coasts.
11th century
The power of Pisa as a mighty maritime nation began to grow and reached its apex in the 11th century when it acquired traditional fame as one of the four main historical Maritime Republics of Italy (Repubbliche Marinare).
At that time, the city was a very important commercial centre and controlled a significant Mediterranean merchant fleet and navy. It expanded its powers by the sack in 1005 of Reggio Calabria in the south of Italy. Pisa was in continuous conflict with the Saracens, who had their bases in Corsica, for control of the Mediterranean. In 1017 Sardinian Giudicati were military supported by Pisa, in alliance with Genoa, to defeat the Saracen king Mugahid that settled a logistic base on the north of Sardinia the year before. This victory gave Pisa the supremacy in the Tyrrhenian Sea. When the Pisans subsequently ousted the Genoese from Sardinia, a new conflict and rivalry was born between these mighty marine republics. Between 1030 and 1035, Pisa went on to successfully defeat several rival towns in Sicily and conquer Carthage in North Africa. In 1051–1052 the admiral Jacopo Ciurini conquered Corsica, provoking more resentment from the Genoese. In 1063 admiral Giovanni Orlando, coming to the aid of the Norman Roger I, took Palermo from the Saracen pirates. The gold treasure taken from the Saracens in Palermo allowed the Pisans to start the building of their cathedral and the other monuments which constitute the famous Piazza del Duomo.
In 1060 Pisa had to engage in their first battle with Genoa. The Pisan victory helped to consolidate its position in the Mediterranean. Pope Gregory VII recognised in 1077 the new "Laws and customs of the sea" instituted by the Pisans, and emperor Henry IV granted them the right to name their own consuls, advised by a Council of Elders. This was simply a confirmation of the present situation, because in those years the marquis had already been excluded from power. In 1092 Pope Urban II awarded Pisa the supremacy over Corsica and Sardinia, and at the same time raising the town to the rank of archbishopric.
Pisa sacked the Tunisian city of Mahdia in 1088. Four years later Pisan and Genoese ships helped Alfonso VI of Castilla to push El Cid out of Valencia. A Pisan fleet of 120 ships also took part in the First Crusade and the Pisans were instrumental in the taking of Jerusalem in 1099. On their way to the Holy Land the ships did not miss the occasion to sack some Byzantine islands: the Pisan crusaders were led by their archbishop Daibert, the future patriarch of Jerusalem. Pisa and the other Repubbliche Marinare took advantage of the crusade to establish trading posts and colonies in the Eastern coastal cities of the Levant. In particular the Pisans founded colonies in Antiochia, Acre, Jaffa, Tripoli, Tyre, Latakia and Accone. They also had other possessions in Jerusalem and Caesarea, plus smaller colonies (with lesser autonomy) in Cairo, Alexandria and of course Constantinople, where the Byzantine Emperor Alexius I Comnenus granted them special mooring and trading rights. In all these cities the Pisans were granted privileges and immunity from taxation, but had to contribute to the defence in case of attack. In the 12th century the Pisan quarter in the Eastern part of Constantinople had grown to 1,000 people. For some years of that century Pisa was the most prominent merchant and military ally of the Byzantine Empire, overcoming Venice itself.

12th century
In 1113 Pisa and the Pope Paschal II set up, together with the count of Barcelona and other contingents from Provence and Italy (Genoese excluded), a war to free the Balearic Islands from the Moors: the queen and the king of Majorca were brought in chains to Tuscany. Even though the Almoravides soon reconquered the island, the booty taken helped the Pisans in their magnificent programme of buildings, especially the cathedral and Pisa gained a role of pre-eminence in the Western Mediterranean.
In the following years the mighty Pisan fleet, led by archbishop Pietro Moriconi, drove away the Saracens after ferocious combats. Though short-lived, this success of Pisa in Spain increased the rivalry with Genoa. Pisa's trade with the Languedoc and Provence (Noli, Savona, Fréjus and Montpellier) were an obstacle to the Genoese interests in cities like Hyères, Fos, Antibes and Marseille.
The war began in 1119 when the Genoese attacked several galleys on their way to the motherland, and lasted until 1133. The two cities fought each other on land and at sea, but hostilities were limited to raids and pirate-like assaults.
In June 1135, Bernard of Clairvaux took a leading part in the Council of Pisa, asserting the claims of pope Innocent II against those of pope Anacletus II, who had been elected pope in 1130 with Norman support but was not recognised outside Rome. Innocent II resolved the conflict with Genoa, establishing the sphere of influence of Pisa and Genoa. Pisa could then, unhindered by Genoa, participate in the conflict of Innocent II against king Roger II of Sicily. Amalfi, one of the Maritime Republics (though already declining under Norman rule), was conquered on 6 August 1136: the Pisans destroyed the ships in the port, assaulted the castles in the surrounding areas and drove back an army sent by Roger from Aversa. This victory brought Pisa to the peak of its power and to a standing equal to Venice. Two years later its soldiers sacked Salerno.
In the following years Pisa was one of the staunchest supporters of the Ghibelline party. This was much appreciated by Frederick I. He issued in 1162 and 1165 two important documents, with the following grants: apart from the jurisdiction over the Pisan countryside, the Pisans were granted freedom of trade in the whole Empire, the coast from Civitavecchia to Portovenere, a half of Palermo, Messina, Salerno and Naples, the whole of Gaeta, Mazara and Trapani, and a street with houses for its merchants in every city of the Kingdom of Sicily. Some of these grants were later confirmed by Henry VI, Otto IV and Frederick II. They marked the apex of Pisa's power, but also spurred the resentment of cities like Lucca, Massa, Volterra and Florence, who saw their aim to expand towards the sea thwarted. The clash with Lucca also concerned the possession of the castle of Montignoso and mainly the control of the Via Francigena, the main trade route between Rome and France. Last but not least, such a sudden and large increase of power by Pisa could only lead to another war with Genoa.
Genoa had acquired a largely dominant position in the markets of Southern France. The war began presumably in 1165 on the Rhône, when an attack on a convoy, directed to some Pisan trade centres on the river, by the Genoese and their ally, the count of Toulouse failed. Pisa on the other hand was allied to Provence. The war continued until 1175 without significant victories. Another point of attrition was Sicily, where both the cities had privileges granted by Henry VI. In 1192, Pisa managed to conquer Messina. This episode was followed by a series of battles culminating in the Genoese conquest of Syracuse in 1204. Later, the trading posts in Sicily were lost when the new Pope Innocent III, though removing the excommunication cast over Pisa by his predecessor Celestine III, allied himself with the Guelph League of Tuscany, led by Florence. Soon he stipulated a pact with Genoa too, further weakening the Pisan presence in Southern Italy.
To counter the Genoese predominance in the southern Tyrrhenian Sea, Pisa strengthened its relationship with their Spanish and French traditional bases (Marseille, Narbonne, Barcelona, etc.) and tried to defy the Venetian rule of the Adriatic Sea. In 1180 the two cities agreed to a non-aggression treaty in the Tyrrhenian and the Adriatic, but the death of Emperor Manuel Comnenus in Constantinople changed the situation. Soon there were attacks on Venetian convoys. Pisa signed trade and political pacts with Ancona, Pula, Zara, Split and Brindisi: in 1195 a Pisan fleet reached Pola to defend its independence from Venice, but the Serenissima managed soon to reconquer the rebel sea town.
One year later the two cities signed a peace treaty which resulted in favourable conditions for Pisa. But in 1199 the Pisans violated it by blockading the port of Brindisi in Puglia. In the following naval battle they were defeated by the Venetians. The war that followed ended in 1206 with a treaty in which Pisa gave up all its hopes to expand in the Adriatic, though it maintained the trading posts it had established in the area. From that point on the two cities were united against the rising power of Genoa and sometimes collaborated to increase the trading benefits in Constantinople.

13th century
In 1209 there were in Lerici two councils for a final resolution of the rivalry with Genoa. A twenty-year peace treaty was signed. But when in 1220 the emperor Frederick II confirmed his supremacy over the Tyrrhenian coast from Civitavecchia to Portovenere, the Genoese and Tuscan resentment against Pisa grew again. In the following years Pisa clashed with Lucca in Garfagnana and was defeated by the Florentines at Castel del Bosco. The strong Ghibelline position of Pisa brought this town diametrically against the Pope, who was in a strong dispute with the Empire. And indeed the pope tried to deprive the town of its dominions in northern Sardinia.
In 1238 Pope Gregory IX formed an alliance between Genoa and Venice against the empire, and consequently against Pisa too. One year later he excommunicated Frederick II and called for an anti-Empire council to be held in Rome in 1241. On 3 May 1241, a combined fleet of Pisan and Sicilian ships, led by the Emperor's son Enzo, attacked a Genoese convoy carrying prelates from Northern Italy and France, next to the Isola del Giglio, in front of Tuscany: the Genoese lost 25 ships, while about thousand sailors, two cardinals and one bishop were taken prisoner. After this outstanding victory the council in Rome failed, but Pisa was excommunicated. This extreme measure was only removed in 1257. Anyway, the Tuscan city tried to take advantage of the favourable situation to conquer the Corsican city of Aleria and even lay siege to Genoa itself in 1243.
The Ligurian republic of Genoa, however, recovered fast from this blow and won back Lerici, conquered by the Pisans some years earlier, in 1256.
The great expansion in the Mediterranean and the prominence of the merchant class urged a modification in the city's institutes. The system with consuls was abandoned and in 1230 the new city rulers named a Capitano del Popolo ("People's Chieftain") as civil and military leader. In spite of these reforms, the conquered lands and the city itself were harassed by the rivalry between the two families of Della Gherardesca and Visconti. In 1237 the archbishop and the Emperor Frederick II intervened to reconcile the two rivals, but the strains did not cease. In 1254 the people rebelled and imposed twelve Anziani del Popolo ("People's Elders") as their political representatives in the Commune. They also supplemented the legislative councils, formed of noblemen, with new People's Councils, composed by the main guilds and by the chiefs of the People's Companies. These had the power to ratify the laws of the Major General Council and the Senate.

Decline
The decline began on 6 August 1284, when the numerically superior fleet of Pisa, under the command of Albertino Morosini, was defeated by the brilliant tactics of the Genoese fleet, under the command of Benedetto Zaccaria and Oberto Doria, in the dramatic naval Battle of Meloria. This defeat ended the maritime power of Pisa and the town never fully recovered: in 1290 the Genoese destroyed forever the Porto Pisano (Pisa's Port), and covered with salt. The region around Pisa did not permit the city to recover from the loss of thousands of sailors from the Meloria, while Liguria guaranteed enough sailors to Genoa. Goods continued to be traded, albeit in reduced quantity, but the end came when the River Arno started to change course, preventing the galleys from reaching the city's port up the river. It seems also that nearby area became infested with malaria. Within 1324 also Sardinia was entirely lost in favour of the Aragonese.
Always Ghibelline, Pisa tried to build up its power in the course of the 14th century and even managed to defeat Florence in the Battle of Montecatini (1315), under the command of Uguccione della Faggiuola. Eventually, however, divided by internal struggles and weakened by the loss of its mercantile strength, Pisa was conquered by Florence in 1406. In 1409 Pisa was the seat of a council trying to set the question of the Great Schism. Furthermore in the 15th century, access to the sea became more and more difficult, as the port was silting up and was cut off from the sea. When in 1494 Charles VIII of France invaded the Italian states to claim the Kingdom of Naples, Pisa grabbed the opportunity to reclaim its independence as the Second Pisan Republic.
But the new freedom did not last long. After fifteen years of battles and sieges, Pisa was reconquered in 1509 by the Florentine troops led by Antonio da Filicaja, Averardo Salviati and Niccolò Capponi. Its role of major port of Tuscany went to Livorno. Pisa acquired a mainly, though secondary, cultural role spurred by the presence of the University of Pisa, created in 1343. Its decline is clearly shown by its population, which has remained almost constant since the Middle Ages.
Pisa was the birthplace of the important early physicist, Galileo Galilei. It's still the seat of an archbishopric; it has become a light industrial centre and a railway hub. It suffered repeated destruction during World War II.

Main sights
While the Leaning Tower is the most famous image of the city, it is one of many works of art and architecture in the city's Piazza del Duomo, also known, since 20th century, as Piazza dei Miracoli (Square of Miracles), to the north of the old town center. The Piazza del Duomo also houses the Duomo (the Cathedral), the Baptistry and the Camposanto Monumentale (the monumental cemetery).
Other interesting sights include:
Pisa boasts several museums:
Pisa hosts the University of Pisa, especially renowned in the fields of Physics, Mathematics, Engineering and Computer Science, the Scuola Superiore Sant'Anna and the Scuola Normale Superiore, the Italian academic élite institutions, mostly for research and the education of graduate students.
Construction of a new leaning tower of glass and steel 57 meters tall, containing offices and apartments was scheduled to start in summer 2004 and take 4 years. It was designed by Dante Oscar Benini and raised criticism.
Other interesting sights include:
- Knights' Square (Piazza dei Cavalieri), where the Palazzo della Carovana, with its impressive façade designed by Giorgio Vasari may be seen.
- In the same place is the church of Santo Stefano dei Cavalieri, also by Vasari. It had originally a single nave; two more were added in the 17th century. It houses a bust by Donatello, and paintings by Vasari, Jacopo Ligozzi, Alessandro Fei, and Jacopo Chimenti da Empoli. It also contains spoils from the many naval battles between the Cavalieri (Knights of St. Stephan) and the Turks between the 16–18th century, including the Turkish battle pennant hoisted from Ali Pacha's flagship at the 1571 Battle of Lepanto.
- Also close to the square is the small church of St. Sixtus. It was formally consecrated in 1133, but previously used as a seat of the most important notarial deeds of the town , also hosting the Council of Elders. It is today one of the best preserved early Romanesque buildings in town.
- The church of St. Francis, designed by Giovanni di Simone, built after 1276. In 1343 new chapels were added and the church was elevated. It has a single nave and a notable belfry, as well as a 15th‑century cloister. It houses works by Jacopo da Empoli, Taddeo Gaddi and Santi di Tito. In the Gherardesca Chapel are buried Ugolino della Gherardesca and his sons.
- Church of San Frediano, built by 1061, has a basilica interior with three aisles, with a crucifix from the 12th century. 16th century paintings were added during a restoration, including works by Ventura Salimbeni, Domenico Passignano, Aurelio Lomi, and Rutilio Manetti.
- Church of San Nicola, built by 1097, was enlarged between 1297 and 1313 by the Augustinians, perhaps by the design of Giovanni Pisano. The octagonal belfry is from the second half of the 13th century. The paintings include the Madonna with Child by Francesco Traini (14th century) and St. Nicholas Saving Pisa from the Plague (15th century). Noteworthy are also the wood sculptures by Giovanni and Nino Pisano, and the Annunciation by Francesco di Valdambrino.
- The small church of Santa Maria della Spina, attributed to Lupo di Francesco (1230), is another excellent Gothic building.
- The church of San Paolo a Ripa d'Arno, founded around 952 and enlarged in the mid-12th century along lines similar to those of the Cathedral. It is annexed to the Romanesque Chapel of St. Agatha, with an unusual pyramidal cusp or peak.
- The Borgo Stretto, a neighborhood where one can stroll beneath medieval arcades and the Lungarno, the avenues along the river Arno. It includes the Gothic-Romanesque church of San Michele in Borgo (990). Remarkably, there are at least two other leaning towers in the city, one at the southern end of central Via Santa Maria, the other halfway through the Piagge riverside promenade.
- The Medici Palace, once a possession of the Appiano family, who ruled Pisa in 1392–1398. In 1400 the Medici acquired it, and Lorenzo de' Medici sojourned here.
- The Orto botanico di Pisa is Europe's oldest university botanical garden.
- The Palazzo Reale ("Royal Palace"), once of the Caetani patrician family. Here Galileo Galilei showed to Grand Duke of Tuscany the planets he had discovered with his telescope. The edifice was erected in 1559 by Baccio Bandinelli for Cosimo I de Medici, and was later enlarged including other palaces.
- Palazzo Gambacorti, a Gothic building of the 14th century, is now the town hall. The interior shows frescoes boasting Pisa's sea victories.
- Palazzo Agostini, a Gothic building also known as Palazzo dell'Ussero, with its 15th century façade and remains of the ancient city walls dating back to before 1155. The name of the building comes from the coffee rooms of Caffè dell’Ussero, historic meeting place founded on 1 September 1775.
- The mural Tuttomondo, the last public work of Keith Haring, on the rear wall of the convent of the Church of Sant'Antonio, painted in June 1989.
Pisa boasts several museums:
- Museo dell'Opera del Duomo: exhibiting among others the original sculptures of Nicola Pisano and Giovanni Pisano and the treasures of the cathedral.
- Museo delle Sinopie: showing the sinopias from the camposanto, the monumental cemetery. These are red ocher underdrawings for frescoes, made with reddish, greenish or brownish earth colour with water.
- Museo Nazionale di S. Matteo: exhibiting sculptures and painting from 12th century–15th century, among them the masterworks of Giovanni and Andrea Pisano, the Master of San Martino, Simone Martini, Nino Pisano and Masaccio.
- Museo Nazionale di Palazzo Reale: exhibiting the belongings of the families that lived in the palace: paintings, statues, armors, etc.
- Museo Nazionale degli Strumenti per il Calcolo: exhibiting a collection of instruments used in science, between whose a pneumatic machine of Van Musschenbroek and a compass probably belonged to Galileo Galilei.
- Museo di storia naturale e del territorio dell'Università di Pisa, located in the Certosa di Calci, outside the city. It houses one of the largest cetacean skeletons collection in Europe.
Pisa hosts the University of Pisa, especially renowned in the fields of Physics, Mathematics, Engineering and Computer Science, the Scuola Superiore Sant'Anna and the Scuola Normale Superiore, the Italian academic élite institutions, mostly for research and the education of graduate students.
Construction of a new leaning tower of glass and steel 57 meters tall, containing offices and apartments was scheduled to start in summer 2004 and take 4 years. It was designed by Dante Oscar Benini and raised criticism.

Leaning Tower of Pisa
The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply the Tower of Pisa (Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Square (Piazza del Duomo) after the Cathedral and the Baptistry.
The height of the tower is 55.86 m (183.27 ft) from the ground on the low side and 56.70 m (186.02 ft) on the high side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means that the top of the tower is displaced horizontally 3.9 metres (12 ft 10 in) from where it would be if the structure were perfectly vertical.
A popular tourist activity is to pose for photographs pretending to "hold up" the leaning tower and preventing it from falling. The illusion is created through the principle of forced perspective.

Construction
Construction of the tower occurred in three stages across 177 years. Work on the ground floor of the white marble campanile began on August 8, 1173, during a period of military success and prosperity. This ground floor is a blind arcade articulated by engaged columns with classical Corinthian capitals.
The tower began to sink after construction had progressed to the second floor in 1178. This was due to a mere three-metre foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was subsequently halted for almost a century, because the Republic of Pisa was almost continually engaged in battles with Genoa, Lucca and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198 clocks were temporarily installed on the third floor of the unfinished construction.
In 1272 construction resumed under Giovanni di Simone, architect of the Camposanto. In an effort to compensate for the tilt, the engineers built upper floors with one side taller than the other. Because of this, the tower is actually curved. Construction was halted again in 1284, when the Pisans were defeated by the Genoans in the Battle of Meloria.
The seventh floor was completed in 1319. It was built by Tommaso di Andrea Pisano, who succeeded in harmonizing the Gothic elements of the bell-chamber with the Romanesque style of the tower. There are seven bells, one for each note of the musical major scale. The largest one was installed in 1655. The bell-chamber was finally added in 1372.
After a phase (1990–2001) of structural strengthening, the tower is currently undergoing gradual surface restoration, in order to repair visual damage, mostly corrosion and blackening. These are particularly pronounced due to the tower's age and its exposure to wind and rain.

Timeline
There has been controversy about the real identity of the architect of the Leaning Tower of Pisa. For many years, the design was attributed to Guglielmo and Bonanno Pisano, a well-known 12th-century resident artist of Pisa, famous for his bronze casting, particularly in the Pisa Duomo. Bonanno Pisano left Pisa in 1185 for Monreale, Sicily, only to come back and die in his home town. A piece of cast with his name was discovered at the foot of the tower in 1820, but this may be related to the bronze door in the façade of the cathedral that was destroyed in 1595. However recent studies seem to indicate Diotisalvi as the original architect due to the time of construction and affinity with other Diotisalvi works, notably the bell tower of San Nicola and the Baptistery, both in Pisa. However, he usually signed his works and there is no signature by him in the bell tower which leads to further speculation.
History following construction
Galileo Galilei is said to have dropped two cannon balls of different masses from the tower to demonstrate that their speed of descent was independent of their mass. However, this is considered an apocryphal tale, its only source being Galileo's secretary.
During World War II, the Allies discovered that the Germans were using the tower as an observation post. A U.S. Army sergeant was briefly entrusted with the fate of the tower and his decision not to call in an artillery strike kept the tower from being destroyed.
- On January 5, 1172, Donna Berta di Bernardo, a widow and resident of the house of dell'Opera di Santa Maria, bequeathed sixty soldi to the Opera Campanilis petrarum Sancte Marie. The sum was then used toward the purchase of a few stones which still form the base of the bell tower.
- On August 9, 1173, the foundations of the Tower were laid.
- Nearly four centuries later Giorgio Vasari wrote : "Guglielmo, according to what is being said, in [this] year 1174 with Bonanno as sculptor, laid the foundations of the belltower of the cathedral in Pisa."
- Another possible builder is Gerardo di Gerardo. His name appears as a witness to the above legacy of Berta di Bernardo as "Master Gerardo", and as a worker whose name was Gerardo.
- A more probable builder is Diotisalvi, because of the construction period and the structure's affinities with other buildings in Pisa. But he usually signed his works, and there is no signature by him in the belltower.
- Giovanni di Simone was heavily involved in the completion of the tower, under the direction of Giovanni Pisano, who at the time was master builder of the Opera di Santa Maria Maggiore. He could be the same Giovanni Pisano who completed the belfry tower.
- Giorgio Vasari indicates that Tommaso di Andrea Pisano was the designer of the belfry between 1360 and 1370.
- On December 27, 1233, the worker Benenato, son of Gerardo Bottici, oversaw the continuation of the construction of the belltower.
- On February 23, 1260, Guido Speziale, son of Giovanni, a worker on the cathedral Santa Maria Maggiore, was elected to oversee the building of the Tower.
- On April 12, 1264, the master builder Giovanni di Simone and 23 workers went to the mountains close to Pisa to cut marble. The cut stones were given to Rainaldo Speziale, worker of St. Francesco.

On February 27, 1964, the government of Italy requested aid in preventing the tower from toppling. It was, however, considered important to retain the current tilt, due to the vital role that this element played in promoting the tourism industry of Pisa.
A multinational task force of engineers, mathematicians and historians gathered on the Azores islands to discuss stabilization methods. It was found that the tilt was increasing in combination with the softer foundations on the lower side. Many methods were proposed to stabilize the tower, including the addition of 800 tonnes of lead counterweights to the raised end of the base.
In 1987 the tower was declared as part of the Piazza del Duomo UNESCO World Heritage Site along with the neighbouring cathedral, baptistery and cemetery.
On January 7, 1990, after over two decades of stabilization studies, the tower was closed to the public. The bells were removed to relieve some weight, and cables were cinched around the third level and anchored several hundred meters away. Apartments and houses in the path of the tower were vacated for safety. The final solution to prevent the collapse of the tower was to slightly straighten the tower to a safer angle, by removing 38 cubic meters (50 cubic yards) of soil from underneath the raised end. The tower was straightened by 45 centimeters (18 inches), returning to its 1838 position. After a decade of corrective reconstruction and stabilization efforts, the tower was reopened to the public on December 15, 2001, and was declared stable for at least another 300 years.
In May 2008, after the removal of another 70 metric tons (77 short tons) of earth, engineers announced that the Tower had been stabilized such that it had stopped moving for the first time in its history. They stated it would be stable for at least 200 years.
Alternative candidates
Two German churches have challenged the tower's status as the world's most lop-sided building: the 15th-century square Leaning Tower of Suurhusen and the 14th century bell tower in the town of Bad Frankenhausen. Guinness World Records measured the Pisa and Suurhusen towers, finding the former's tilt to be 3.97 degrees. In June 2010 Guinness World Records certified the Capital Gate building in Abu Dhabi, UAE as the "World's Furthest Leaning Man-made Tower". The Capital Gate tower has an 18-degree slope, almost five times more than the Pisa Tower; however the Capital Gate tower has been deliberately engineered to slant.

About the 5th bell: The name Pasquareccia comes from Easter, because it used to ring on Easter day. However, this bell is older than the bell-chamber itself, and comes from the tower Vergata in Palazzo Pretorio in Pisa, where it was called La Giustizia (The Justice). The bell was tolled to announce executions of criminals and traitors, including Count Ugolino in 1289. A new bell was installed in the belltower at the end of the 18th century to replace the broken Pasquareccia.
