The ivy-covered church has been rebuilt and altered many times in its history. In 1276, it was damaged by fire and modified. The choir dates from the 13th century, while the southern nave dates from the 15th century. In 1622, it was redecorated in Baroque style. It was also somewhat damaged by shellfire during World War II and affected by the demolition of the nearby ruins of another building. In the middle of the apse, there are two Romanesque stained-glass windows.
