Fodor's Expert Review Fortress of St. Michael

This fortress guards the city below from atop a steep, rocky hill. Dating back to the 11th century and re-fortified over the years, it was once the city's main point of defense. Today, a climb to the top grants you vistas of the sea, surrounding islands, and the medieval town. On occassion, special events and concerts are held on an open-air stage on the fortress.
