The first traces of the church of Barbassolo date from the 12C. The present appearance is fruit of a radical restoration project undertaken in the middle of the last century. The Romanesque imprint of the building is clear in the nave with no aisles, the recycled materials of Roman origin, the walls and the quadrangular structure of the bell-tower.

The church, dedicated to physician saints Cosmas and Damian, was recently elevated to the status of sanctuary.
