Originally a promontory attached to the mainland, now separated by a moat, this area is known for its two peaks (koryphi in Greek), which gave the town and the island their modern names. A castle crowns each peak; you can get fine views of Albania to the east and Corfu, town and island, to the west. The promontory itself, for a long time, was the main town, and it appears as such in many old engravings. The Venetians dug the moat in the 16th century; it successfully held off several attempts by the Turks to conquer this outpost of Christianity. What looks like a Greek temple at the south side is in fact a British church (ca. 1830). In summer, a sound-and-light show is held several nights a week (in different foreign languages, so be sure to check the schedule).
