This charming fortified city, built on a promontory, resembles a miniature Dubrovnik. Separated from the mainland by just 1 270m, it protected the island against potential invaders. At its zenith in the 16C, it had 6 000 inhabitants. When times were less troubled, from the 18C onwards, it began to spread outside of its walls along the two bays which encircle the town. The architectural details visible in the streets, particularly musical motifs, are a reminder of the island's great traditions.
