I was happy to see that the Bell Tower in Pisa was still leaning but also glad to know that it has been stabilized, so we can expect it to stay in that position for how long? They aren't sure. It is interesting to note that all the buildings in Pisa are leaning slightly due to the sandy soil ......at least that is the reason given. The Tower had been closed for many years but you can now walk to the top for a fantastic view of the city. Pisa is also the birthplace of Fibonacci of the famous mathematical series.
