response: Yes I do. It actually began to tilt during its construction during the 12th century and that was caused by the foundation that was inadequate, the ground was too soft
original_response: Yep. It's actually caused by inadequate foundation on the ground. It's too soft on one side, so the tower began to tilt in the 12th century. Someone really messed up!
history: i want to visit Italy so bad I see. Did you know that Italy has World Heritage sites ? In fact, it has more than any other nation really? i would like to know more! Yeah! World Heritage Sites are selected by UNESCO, based on their historical and cultural significance. so what are some of those world heritage sites? I don't have this information. But i can assure you that no other country has more of those sites than italy Good to know that. I want to visit Pisa. Cool. Did you know that besides the leaning tower it is known for, Pisa also has over 20 historic churches, and medieval palaces as well? oh, i think i've heard about it. do you know why the tower of Pisa is leaning?
knowledge: The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight.
