Situated on a peninsula in the Black Sea, connected with the mainland by a narrow isthmus, this is a town with a history going back millennia. Each era has left its permanent marks and today the town is unique. A huge museum displays the way of life of the different people that have inhabited it. On this tiny island castle walls from Thracian times, defensive structures, private and public buildings from the Hellenistic period, medieval churches and renaissance buildings combine to form a unique atmosphere. Nearby is the famous sea resort of "Slunchev Briag".
