Every day, thousands of tourists converge on Piazza della Signoria but only a few know it has a truly grim past. For example, no one knows how many people were killed at Palazzo Vecchio, but we can affirm with certainty that Baldaccio d’Anghiari (a mercenary captain from the province of Arezzo) was wrongfully accused of treason and brutally murdered there on September 6, 1441. Nothing strange about the whole story so far, but let’s see what happened 560 years later. In 2001, on a summer night, a boy and his girlfriend went out for a romantic stroll at the Piazzale Michelangelo and recorded the occasion with some pics. The next day, viewing the images on the computer, they realized there was an eerie face staring back at them from one of the pictures and decided to send it to some experts. The photo was analyzed and turned out to be genuine (the detail that makes you jump is that the translucent figure seems to indicate exactly Palazzo Vecchio…); after further research, the paranormal investigators concluded that it was the ghost of Baldaccio d’Anghiari, unsurprisingly unable to find peace.
