What is now known as the Leaning Tower of Pisa and the Venerable Cathedral, The Cathedral and Campanile in the early 1900s can be seen in Pisa, Italy standing 178ft. high with a lean of 19ft. The lean of the tower is due to the way that the foundation is settled but was only noticed after three stories were built. At the same time, war broke out between the Italian city-states and construction came to a halt. Once construction began again, the architect Giovanni di Simone was faced with some major issues until the building topped out and was completed. Today it is a well-visited landmark in Italy and can be toured by visitors.
