The Church of St Gregory
The Church of St Gregory is along the road between Castel Ritaldi and Colle del Marchese. The façade, which was restored after the earthquake of 1997, features horizontal strips of white and red stone, into which a recessed door opens.
The entrance archway, above which the date of the competition of the façade (1141) is inscribed, is decorated with a sequence of scenes and figures: in the lower left is a lion in whose mouth is a spray of raceme that continues along the entire lunette all the way to the mouth of another lion at the other end.
