The Campo dei Miracoli in Pisa, or the Square of Miracles, was proclaimed a World Heritage Site by UNESCO 25 years ago. The square is not located in the center of the city as you might imagine but to the north-west of the fortified wall, almost out of the town; there probably wasn’t enough space to use at the time the project got underway so this is the site decided upon. Since the times of the Etruscans, the three structures found in the piazza have been considered central to religious life, symbolizing the main stages of a human’s life https://www.discovertuscany.com/pisa/piazza-dei-miracoli.html
