We've put together some intriguing and little-known facts about the Leaning Tower, facts we hope will entice you to pay it a visit.

1. Why does the Tower tilt?

When designing the Tower, a tilt was probably not part of the original plans. However, the architects overlooked the fact that it was to be built on marshy swampland.

The name 'Pisa' actually means 'marshy land' in Greek, so it's a little surprising that the presence of water-logged land wasn't spotted.

When the builders reached the second story, the Tower began to slowly sink. Work continued to cause headaches for the builders who desperately attempted to compensate for the tilt by adding height to the opposite side. It soon became obvious that this wouldn't work and building stopped for nearly two centuries. The Tower was eventually finished, complete with the famous tilt.

While historians generally agree that building on the Tower started in 1173, they can't agree on who actually designed it.

Some evidence points to a local architect, Bonanno Pisano as the architect with construction overseen by master-craftsman, Diotisalvi.

He had a habit of signing his work and as the Tower carries no signature, confirmation of this remains elusive.

One, in particular, has acquired a sinister nickname. Every time someone was put to death for treason in the city, the Bell of the Traitor tolled.

To prevent worrisome vibrations, the bells have remained silent for over a century.
