On this day in 1173, the construction of the Tower of Pisa started. We gathered 4 facts about the site:
The tower in numbers: 199 years to build, 57 m high, ~4° of leaning (4 m from the vertical).
The style: Romanesque with thick walls, small windows, and heavy marble.
The tower was meant to be straight but started to sink because of the soft soil underneath.
The building is actually a bell tower: there are 7 bells on its top. However, the bells haven't rung since the last century because their vibrations can make the tower lean more.
