On this high-definition camera we show you Piazza del Popolo, in the historical centre of Todi, a hilltop town in the Italian province of Perugia (Umbria region). Here you can see the Captain’s Palace and the People’s Palace, and on the other edge of this square you will find Todi Cathedral, whose facade has a rose window. Did you know that beneath this square are two Roman cisterns that belong to a series of underground tunnels dating back to the 2nd century B.C.
