Pisa


Our next stop was to visit the famous Leaning Tower of Pisa. Perhaps you may not know that it is actually a bell tower. In most of the photos I have seen, you see the tower by itself, but actually there is a Cathedral right next to it.

Why does the tower lean? Glad you asked! It was actually built on unstable, uneven soil-mostly sand & clay--actually a riverbed. The weight of the tower started to compress the soil and sink, and there's where the lean came in.

Over the years, many things have been tried to right the tower. Mussolini had concrete poured into the foundation, but this only served to make it sink more. The final solution was to remove some soil from the raised end to stabilize it.

Next: Monte Carlo!
