The abbey was built in the year 980 by Benedictine monks over the remains of a previous Roman temple. It was part of a large complex consisting of a monastery with cloister, of a cemetery, of the houses and factory of the Feudal working people. Of such a majestic building only the church in Romanesque style, the white stone portal with a double lancet window above are left. The existence of a previous Roman temple has been documented by many findings: coins, carved stones, tombstones. Particular interesting is the capital, where three human decorations dating back to the 8^th century make us believe that a church existed before the abbey.
