It would be great but it is famous for a building defect, how great can that be.

The Leaning Tower is another building that is unique. The structure is beautiful but obviously it's known for being slightly on its side. I doubt it would be famous or would be even standing today if it weren't for the fact that the building was built on soft clay that made it tilt like that. Yet it is quite an interesting site seeing the building as you walk to the main piazza in Pisa. As you walk in, it seems as if it is at a steep angle, but as you approach it, it looks normal. The history surrounding it is long and interesting. Galileo did experiments on gravity from the tower. It's quite a sight, but architecturally nothing really noteworthy.
