Location of Tower of Pisa
The Tower of Pisa is located in Piazza del Duomo, Italy. The
Tower of Pisa is the freestanding bell tower, of the cathedral of
the Italian city of Pisa.
Facts About Tower of Pisa
 The tower's tilt began during construction,
caused by an inadequate foundation on the
ground.
 Construction was subsequently halted for
almost a century, because the republic of Pisa
was almost continually engaged in battles with
Genoa, Lucca, and Florence.
 The tower took a total amount of 185 and 195
years to build.
 The use of limestone is the reason why the
tower has not cracked and or broken- the rock is
flexible enough that it can withstand the
pressures placed on it.
