Syros is a Greek island in the Cyclades, in the Aegean Sea.
It is located 78 nautical miles (144 km) south-east of Athens. The island is home to the municipalities of Ermoupoli, Ano Syros, and Poseidonia. Ermoupoli is the capital of the island and the Cyclades.
It has always been a significant port town, and during the 19th century it was even more significant than Piraeus.
Ano Syros is the second town of Syros and was built by the Venetians at the beginning of the 13th century on the hill of San Giorgio, north-west of Hermoupolis.
Ano Syros maintains its enchanting medieval atmosphere. Innumerable steps between narrow streets and houses with coloured doors lead to the top of the town.
