Beautiful Sými is an hour away by boat from Mandráki, the port of Rhodes. An island of sponge divers and seamen, Sými used to have 30,000 inhabitants before the Second World War and was the richest island in the Dodecanese, despite its small size. Today Sými attracts many visitors thanks to its beautifully preserved neo-classical buildings and the famous Archangel Michael monastery at Panormitis.
