Likely the site had a church since the early medieval times, and is cited on a hill that rises above the town.
The church suffered from looting and damage by Napoleonic French troops in 1799, and remained closed until 1808, when Bernasconi of Rieti, and later the engineer Fedeli pursued a restoration completed in 1825.
The interior has a single nave with two lateral chapels, dedicated respectively to St Antony of Padua and the Virgin of the Immaculate Conception.
Nearby is the church of Santa Maria Del Giglio, also decorated in baroque style.
