The Leaning Tower of Pisa
The leaning tower of Pisa, situated in Pisa, Italy naturally, is actually a free standing bell tower of the cathedral in Pisa. It is the third oldest structure of the cathedral square built in 1173. It began leaning soon after construction thanks to a poorly constructed foundation and a little help from some lose substrate. This means teh tower today leans to the southwest despite initially leaning to the southeast becase the substrate has shifted around a bit since then. It took 177 years to complete the tower which was originally intended as a work of art depsite it’s construction being flawed from the beginning thanks to a three meter foundation. The tower actually began to sink when they began work on the third floor and at this point construction was halted due to the battles being fought at the time.
