The Leaning Tower of Pisa, which is a historical medieval tower is famous for its askew structure. The nature of the foundation has caused the tower to lean a little bit, precisely 5.5 degrees from the straight angle when it was built in the late 14th century. What makes it even more interesting is that architectural experts predicted that the inclination of the tower was increasing every year, and by 2020, the tower would collapse.
However, it has been 20 years since, and the tower still stands tall in its strange position (that some consider an architectural miracle). It is a great place for a photo, so if you are visiting the Leaning Tower of Pisa, make sure you have a camera with you!
