I have added a few photos of my own to my Dad’s post about Orvieto’s stunning Duomo and the nearby Torre di Maurizio.
Snapshots from a Tourist in Italy
Described as the jewel of Romanesque Architecture, it may have been done before. The magnificent façade with the Rose window is one of the enduring images of Orvieto. However, it is for the sides that you appreciate the alternate courses of local tufo (the cream stone) and basalt (the dark grey).
Torre di Maurizio
Near the duomo is the Torre di Maurizio, the tower was originally erected as a sundial.
