Sedir Island was the site of an ancient Roman resort town. Ruins include an amphitheater and old city wall. Its Cleopatra Beach is made up of rare ooids, round calcium carbonate particles from Egypt. According to legend, Cleopatra refused to step on any land other than Egypt, so Mark Antony imported Egyptian sands from Red Sea to Turkey so she could visit. The beach is heavily protected to prevent any sand being removed from the beach.
