Pisa, Italy; September 24, 2000

These are photos I took during a trip to Pisa, Italy on September 24, 2000.

Pisa, Italy

Pisa is a city in Tuscany, central Italy, on the right bank of the mouth of the Arno River on the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its Leaning Tower, bell tower of the cathedral, the city of over 87,500 residents contains more than 20 other historic churches, several palaces, and various bridges across the Arno River.

Piazze del Duomo

The Piazza del Duomo ("Cathedral Square") is a wide, walled area at the heart of the city of Pisa, Tuscany, Italy, recognized as one of the main centers for medieval art in the world. Partly paved and partly grassed, it is dominated by four great religious edifices: the Duomo, the Leaning Tower (the cathedral's campanile), the Baptistry and the Camposanto.
It is otherwise known as Piazza dei Miracoli ("Square of Miracles"). This name was created by the Italian writer and poet Gabriele d'Annunzio who, in his novel Forse che si forse che no (1910) described the square in this way:
L’Ardea roteò nel cielo di Cristo, sul prato dei Miracoli.
which means: "The Ardea rotated over the sky of Christ, over the meadow of Miracles."
Often people tend to mistake the term with Campo dei Miracoli ("Field of Miracles"). This one is a fictional magical field in the book Pinocchio, where a gold coin seed will grow a money tree.
In 1987 the whole square was declared a UNESCO World Heritage Site.

The Baptistry

The Baptistery, dedicated to St. John the Baptist, stands opposite the west end of the Duomo. The round Romanesque building was begun in the mid 12th century: 1153 Mense August fundata fuit haec ("In the month of August 1153 was set up here..."). It was built in Romanesque style by an architect known as Diotisalvi ("God Save You"), who worked also in the church of the Holy Sepulchre in the city. His name is mentioned on a pillar inside, as Diotosalvi magister. the construction was not, however, finished until the 14th century, when the loggia, the top storey and the dome were added in Gothic style by Nicola Pisano and Giovanni Pisano.
It is the largest baptistery in Italy. Its circumference measures 107.25 m. Taking into account the statue of St. John the Baptist (attributed to Turino di Sano) on top of the dome, it is even a few centimetres higher than the Leaning Tower.
The portal, facing the facade of the cathedral, is flanked by two classical columns, while the inner jambs are executed in Byzantine style. The lintel is divided in two tiers. The lower one depicts several episodes in the life of St. John the Baptist, while the upper one shows Christ between the Madonna and St John the Baptist, flanked by angels and the evangelists.
The immensity of the interior is overwhelming, but it is surprisingly plain and lacks decoration. It has notable acoustics also.
The octagonal font at the centre dates from 1246 and was made by Guido Bigarelli da Como. The bronze sculpture of St. John the Baptist at the centre of the font, is a remarkable work by Italo Griselli.
The pulpit was sculpted between 1255-1260 by Nicola Pisano, father of Giovanni Pisano, the artist who produced the pulpit in the Duomo. The scenes on the pulpit, and especially the classical form of the naked Hercules, show at best Nicola Pisano's qualities as the most important precursor of Italian renaissance sculpture by reinstating antique representations. Therefore, surveys of the Italian Renaissance usually begin with the year 1260, the year that Nicola Pisano dated this pulpit.

The Leaning Tower of Pisa

The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La 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 Piazza del Duomo (Cathedral Square) after the cathedral and the baptistry.
Although intended to stand vertically, the tower began leaning to the southeast soon after the onset of construction in 1173 due to a poorly laid foundation and loose substrate that has allowed the foundation to shift direction. The tower presently leans to the southwest.
The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest 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. The tower leaned at an angle of 5.5 degrees but after the restoration works between 1990 and 2001 the tower leans at an angle of 3.99 degrees. This means that the top of the tower is 3.9 metres (12 ft 10 in) from where it would stand if the tower were perfectly vertical.

Construction

The Tower of Pisa was a work of art, performed in three stages over a period of about 177 years. Construction of the first floor of the white marble campanile began on August 9, 1173, a period of military success and prosperity. This first floor is surrounded by pillars with classical capitals, leaning against blind arches.
The tower began to sink after construction progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil. This means the design was flawed from the beginning. Construction was subsequently halted for almost a century, because the Pisans were 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 higher floors with one side taller than the other. This made the tower begin to lean in the other direction. 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. The bell-chamber was not finally added until 1372. 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 scale. The largest one was installed in 1655.
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 strong due to the tower's age and to its particular conditions with respect to wind and rain.

Timeline

On January 5, 1172, Donna Berta di Bernardo, a widow and resident of the house of dell'Opera di Santa Maria, bequeathed sessanta soldi or "sixty coins" to the Opera Campanilis petrarum Sancte Marie. This money was to be used toward the purchase of a few stones which still form the base of the bell tower today.
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 work of completing 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
