Skarkos (Greek: Σκάρκος) is an early Bronze Age settlement on the island of Ios in Greece.
The settlement of Skarkos is situated on a hill in the middle of the west side of Ios, in proximity to the island's most fertile plains and to its harbour.
They have brought to light an important early Cycladic settlement (mid-3rd millennium BC) in an exceptionally good state of preservation (two-storey buildings, four-metre-high walls), and an overlying late middle/early late Bronze Age cemetery (mid-2nd millennium BC).
The settlement covers an area of 1.1 hectares and is the largest and best preserved site of the Keros-Syros culture, estimated to have been home to between 200 and 300 people.
[3] The urban planning system of Skarkos is comparable to that of Poliochne on Lemnos from the beginning of the 3rd millennium BC.
