The Church of San Silvestro in Bevagna is one of the most significant examples of Umbrian Romanesque architecture. The façade, which remains unfinished, was designed to have two orders and a bell tower, mirroring the nearby church of San Michele. The lower section features a portal richly decorated with vine tendrils and zoomorphic figures carved in bas-relief, whilst above there are two side mullioned windows with twisted columns and a refined central triple-arched window with paired columns, constructed using reused Roman marble. A string course runs along the top, adorned with figurative reliefs depicting hunting scenes and representations of humans and animals.

The interior has a basilica-style plan divided into three naves, separated by simple cylindrical columns with capitals decorated with plant motifs. The chancel, which ends in an apse, is raised above the crypt below, creating a striking visual effect.

Particularly interesting and rare are the roof structures of the side aisles, constructed with semi-barrel vaults, which help to define the church’s original and distinctive architectural character.
