The Tower of Pisa, one of Europe's most famous towers and designed by Bonanno Pisano, is a freestanding bell tower, of the cathedral of the Italian city of Pisa. The Tower of Pisa was a work of art, performed in three stages over a period of about 177 years. It stands 183.27 feet tall from the ground on the shortest side and 186.02 on the highest side. 

Construction of the first floor of the white marble campanile began on August 9, 1173. This first floor is surrounded by pillars with classical capitals, leaning against blind arches.

The tower began to sink after construction progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil and the construction was halted, allowing time for the underlying soil to settle, otherwise, the tower would almost certainly have toppled. 

The construction resumed in 1272. Trying to compensate for the tilt the engineers built higher floors with one side taller than the other. This made the tower begin to lean in the other direction. Because of this, the tower is actually curved. Construction was halted again in 1284.

The seventh floor was completed in 1319. The bell-chamber was not finally added until 1372. There are seven bells in the tower, one for each note of the tuned musical scale. 

After a phase (1990-2001) of structural strengthening, the tower is currently undergoing gradual surface restoration, in order to repair visual damage, mostly corrosion and blackening.

After 2001, the tower reopened to the public. However, the number of visitors is strictly controlled via compulsory 35- to 40-minute guided tours where you are able to climb to the top. There are 294 stairs with no hand rails and the walls are worn smooth. The stairs are slippery and were built in a very tight spiral. You may think it was harder getting down than going up.
