Built between the eighth and ninth century, it was donated to the bishop of Modena by Matilda of Canossa in 1108. The building, in the form of a basilica, rises on a limestone outcrop and is constructed from local sandstone.
The view is quite stunning. Inside it is split into three naves, divided by generous pointed arches which rest on four imposing columns and semi-columns. The capitals, differing in shape and ornamental composition and vigorously sculpted, are considered amongst the most beautiful in North Italy.
