Archaeologists from a university in Pisa believe they have officially confirmed the identity of the city’s famous Leaning Tower. A man by the name of Bonanno Pisano remained a mystery for so long because he was embarrassed of his creation’s tilt.

“The poor man died deluded, never realizing what a marvel it would be centuries later,” Professor Ammannati, a paleography (the study of ancient writing) expert at Pisa’s Scuola Normale Superiore, told the Times of London.
