The original construction of the Chapel of San Grato, which was later incorporated into later extensions, is still partly visible in the side elevation of the current church, which faces the street. The frames that have been preserved reveal that this, to the south, was originally the main facade. Today, however, the church is facing east and has two naves, with the sacristy and the chaplain’s house attached. Inside, completely frescoed, emerges the elegant baroque altar, with a recently restored altar, depicting San Grato, which occupies the space that once belonged to the old chapel. Under the canteen there is a reliquary, certainly belonging to the previous structure, with the relics of San Grato.
