Monastery and Church of St. John the Evangelist is the only medieval sacred building with procession around the altar. Probably built in the pre-Christian period, and restored during the Romanesque period when the 20 m bell tower was added. The basilica changed hands, starting out as a Benedictine monastery to be given to the Franciscans in the 13th century. It was completely ruined in the 19th century.
