Overview
The basilica has a façade in undecorated sandstone, with three bays corresponding to the interior's nave and two aisles. The central one has the main portal, surmounted by a triple mullioned window. The façade is topped by a tympanum also divided into three parts, the central one characterized by a lozenge. Near the pilasters flanking the portal are two old columns, whence it has been hypothesized that the church once had a portico or similar structure.
The side walls are divided into blind arches with Lombard bands, but have few decorations otherwise. More numerous are the features of the apse, with semi-columns supported by plinths and ending in leaf-shaped capitals, Lombard bands and six single-smullioned windows (the three lower ones lighting the church's crypt).
In the interior the aisles and the nave are divided by seven columns with arcades, made of material from ancient settlements of the area. The aisles are covered by groin vaults, while the nave has trusses. The columns in the crypt are original.
