Sifnos Sights & Monuments - The Kastro of Sifnos in Greece is a historical village that served as the old capital of the island. Populated since prehistoric times, Kastro derives its name from the castle-like construction of its buildings. The village comprises of two defensive circles, with adjacent houses built closely to each other. The inner circle consists of rich houses for maximum protection, while the outer one has poor houses. Standing tall at the top of the hill are ruins of the ancient citadel of Kastro, which dates back to the 6th century B.C. Surrounded by a Sifnian marble wall, this citadel is the only one of its kind in the Cyclades that is still preserved today.
