Why did Pisa build a Leaning Tower?
The Leaning Tower of Pisa wasn’t supposed to lean at all. It was supposed to just be the bell tower for the Cathedral of Pisa. It was to hold the bells that rang to tell people when to come to church. But they built the tower in the Early Middle Ages, about 1173 AD. Nobody in Europe had been building anything like that for several hundred years. So the architects were not really experienced.

Why build a tower at all?
This tower looks like the bell tower from the Romanesque church at Toulouse almost 200 years earlier, but it stands alone instead of on top of the church. The architects were probably imitating Islamic minarets, but they didn’t really know what they were doing.
Almovarids and Almohads
Pisa did a lot of trading with the Islamic Empire in North Africa, across the Mediterranean Sea. The Almohads had just gotten into power there. Before the Almohads, the Almovarids had not allowed anyone to build minarets. It was illegal for many years. Then the Almohads conquered the area. To show they had won, the Almohads changed the law and encouraged people to build minarets all over the place.
Pisa probably wanted to build one too – only they were Christian, so they built a bell-tower instead. But they didn’t know much about it, so they did a terrible job. (The original idea for minarets may have come from Chinese Buddhist pagodas.)
So the architects built their bell tower on soft ground, without enough foundations. And as soon as they were done the tower began to slowly tilt over sideways. But very slowly.
Will the Leaning Tower fall down?
Even today, the tower is still tilting over, little by little. It’s been slowly tilting for almost a thousand years, and it still hasn’t fallen down. Though mostly engineers have stopped it now with reinforcements to make it stronger. So it won’t fall down anytime soon.
