About 50 meters up the slopes of a mountain that rises precipitously above the town is another large cave complex, also carved by wave action several million years ago, inside of which is a completely built church of Madonna della Grotta, and an open air sanctuary. Both the church and sanctuary are both in use today. Other sights include the Rocca (14th century), built by the Normans, and the 16th century Fortino ("Small Fort").
