Soak in the dizzying bay views at the belvedere before exploring the adjoining Abbazia di San Michele Arcangelo. Built in the 11th century and remodelled between the 17th and 19th centuries, this one-time Benedictine abbey houses a small museum with some arresting pictures done in gratitude by shipwrecked sailors, plus a church with a spectacular coffered ceiling and an ancient Greek alabaster basin converted into a font, and a maze of catacombs that leads to a tiny secret chapel.
