The Abbey of San Bartolomeo was founded in the 11th century as a Romanesque church, built on the foundations of a Roman villa and a pagan temple. It had a rectangular layout, a main nave, and a secondary one with an oak wood roof, as well as a bell tower. Externally, it displayed typical Romanesque features: exposed bricks, hanging arches, and stone-decorated portals.
In the first half of the 19th century, the original structure was demolished and rebuilt in neoclassical style according to the design of engineer Roncalli: a rectangular plan with an inscribed Greek cross, barrel vault, central dome, semicircular apse, and a walnut wood choir. The interior is enriched by paintings by master Luigi Fontana, stuccos by his student Niccolò Achilli, and the splendid pipe organ by Vincenzo Paci from 1881, restored thanks to the efforts of the Corale San Bartolomeo.
Adjacent to the church, the rectory houses the evocative ‘Hall of Coats of Arms,’ entirely decorated with views of the village and portraits of the commendatory abbots who have succeeded each other from 1564 to the present.
