The Leaning Tower of Pisa is located in Pisa, Italy and is 55.86 meters high. Construction began in 1173 and was not completed until 1370. The tower leans because the ground underneath is too soft. It has leaned as much as 4.5 meters but currently leans at a 3.9 degree angle or 4.1 meters. The tower serves as the bell tower for the cathedral and is one of the oldest structures in the city.

5. Builders
We don't now who build it. One possible builder is
Gerardo di 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 bell tower.
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 (Belgium).

6. The bell
●
About the bell: The name Pasquareccia comes from
Easter, because it used to ring on Easter day. However,
this bell is older than the bell­chamber 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 bell tower at the end of the 18th
century to replace the broken Pasquareccia.
