Sporádes
The Northern Sporades are scattered across the Aegean northeast of Euboea. Among them, Skopelos was known in antiquity as Peparethos, celebrated for its wine, while Skiathos lies farther west toward the mainland. In the 14th century the people of Skiathos moved their chief settlement to a high, steep-sided rock called Kastro for protection from pirates. The Ottoman admiral Hayreddin Barbarossa conquered the Northern Sporades in 1538, ending Venetian rule over Skiathos and Skopelos.
