This is by en-large the main reason people visit Pisa and is a structure that is known worldwide.
The Campanile or bell tower of Pisa Cathedral is a beautiful structure in its own right, but it has been made famous by its noticeable tilt.
Constructed in the 12th century after the cathedral, it was soon found that the foundations were unstable and the building began to lean.
To this day the tower still leans and measures have been taken to ensure it doesn’t collapse.
Aside from posing for funny photos, the architecture of the tower is actually fantastic and the 6 rows of stone arches are simply beautiful.
