The Leaning Tower of Pisa is a freestanding bell tower for the Cathedral of Pisa. The bell tower is situated in Pisa, Italy. It was constructed between 1173 and 1372.
Why it is special: Known simply as the Tower of Pisa, this bell tower is 55.86 metres in height and was completed in stages over a period of 199 years. A total of 7 floors, this Tower earned the name Leaning Tower because after the first 2 floors were constructed the Tower began to sink due to a weak foundation laid in unstable subsoil. Created beautifully with gothic elements fusing seamlessly with a Romanesque style tower, the Tower is a major attraction not just for its architectural beauty but also for its famous tilt.
