This was built in the 14 C and has a dilapidated facade which does not prepare you for the rich interior. There is a cycle of 15C frescoes, an extraordinary apse, a gem of Burgundian Gothic art "embroidered" in green Sampeyre stone, the tomb of Louis II of Saluzzo by Benedetto Briosco (who followed Amadeo to the Carthusian Monastery of Pavia) and the mausoleum of Galeazzo Cavassa all of which will hold your attention.
