The Leaning Tower of Pisa is one of the most remarkable architectural structures from medieval Europe.
It is located in the Italian town of Pisa, one of the most visited European cities.
The Tower of Pisa is located next to the Cathedral of Pisa, in Piazza dei Miracoli (Square of miracles) in the city of Pisa, Italy.
The building of the leaning Tower of Pisa, and especially its completion, represents the last element in the compliment of the ceremonial complex of monuments that enrich the Piazza dei Miracoli (Square of miracles).
The leaning Tower of Pisa is a medieval architecture, in Romanesque style.
Giovanni Pisano and Giovanni di Simone continued the second phase of the building. Tommaso Pisano finished the tower’s construction.
The tower is is famous for the settling of its foundations, which caused it to lean 5.5 degrees (about 15 feet [4.5 metres]) from the perpendicular in the late 20th century. Extensive work was subsequently done to straighten the tower, and its lean was ultimately reduced to less than 4.0 degrees.
The foundations have been strengthened by the injection of cement grout and various types of bracing and reinforcement, but in the late 20th century the structure was still subsiding, at the rate of 0.05 inch (1.2 mm) per year, and was in danger of collapse. In 1990 the tower was closed and all the bells silenced as engineers undertook a major straightening project. Earth was siphoned from underneath the foundations, decreasing the lean by 17 inches (44 cm) to 13.5 feet (4.1 metres); the work was completed in May 2001, and the structure was reopened to visitors. The tower continued to straighten without further excavation, until in May 2008 sensors showed that the motion had finally stopped, at a total improvement of 19 inches (48 cm). Engineers expected the tower to remain stable for at least 200 years.

The construction of Tower of Pisa began in 1173 and was completed in the 14th century, in 1399
It is
considered that the architects and engineers who designed the leaning
Tower of Pisa are: Bonanno Pisano, Gherardo di Gherardo, Giovanni
Pisano, Giovanni di Simone
The first phase of Pisa Tower’s construction is attributed to Bonanno Pisano or Gherardo di Gherardo.Giovanni Pisano and Giovanni di Simone continued the second phase of the building. Tommaso Pisano finished the tower’s construction.
