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

Looming 102 meters over the Piazza del Campo, the elegant, sleek tower to the Palazzo Pubblico is the third tallest in all of Italy. Built from red brick, as a symbol of its affinity to the “commoner” the tower is 87 meters tall of brick and the remaining is a white travertine, most probably to make it visually more prominent. https://www.discovertuscany.com/siena/tower-of-mangia.html

The Medici Chapels form part of the monumental complex of San Lorenzo. The church of San Lorenzo was the official church of the Medici from their period as private residents in their palace in Via Larga (now via Cavour), becoming their mausoleum up to the time of the extinction of the line. https://www.visitflorence.com/florence-churches/medici-chapels.html
