A trip out to Pisa. You could be forgiven for thinking there is nothing in Pisa but a rather awkward tower. Almost correct. There is nothing to see but a walled off square that contains a baptistry, a church, and a tower.
As a show of wealth, the Baptistry leads straight into the church, and at the rear is the impressive tower. Unfortunately it seems the Pisans were not too bright. To demonstrate their wealth the tower is made of solid marble, weighing 14,500 tonnes. It is also built on soft clay and sand, which was never going to support it.
After several attempts, it has now been stabilised.

In this image you have the Baptistry and the city walls of Pisa.
