The Leaning Tower of Pisa is one of the most famous buildings in the world.

But it was never meant to look like this.

In this episode, we explore how a 12th century bell tower in Pisa, Italy, became one of architecture’s most iconic accidents. From the ambition of a powerful maritime republic, to unstable soil, halted construction, and centuries of slow movement, this is the story of how a structural flaw turned into a global symbol.

Along the way, we look at the people behind the project, the medieval builders who tried to adapt to a problem they couldn’t fully control, and the modern engineers who ultimately saved the tower without erasing its identity.

A story of architecture, ambition, and a mistake that refused to disappear.
