Selinus was a Greek colony on the south-west coast of Sicily, some 13 km south of Castelvetrano. It was founded ca. 650 BCE from Megara Hyblaea, on the east coast of Sicily, and flourished as an independent state until it was taken by the Carthaginians in their conquest of 409 BCE; it remained under their rule until abandoned by them in 250 BCE in the face of a Roman attack. The large Temple C on the acropolis (stylobate 23.94 x 63.72 m; probably ca. 550-ca. 525 BCE) displays characteristics of the Sicilian Archaic style, being built to a long, narrow plan of 6 by 17 columns, with a double column front emphasized by a wide stair, a colonnade with thick, heavy columns closely set without corner contraction, and a tall entablature decorated at the eaves and under the pediments with ornamental terracottas. The design was modelled on the early temples of Syracuse. The long, narrow cella was divided into three rooms, with doors in the porch, a cella without inner columns and an adyton (shrine) for the cult image. Both pediments were decorated with large terracotta gorgon masks, as frequently occurred in Archaic Sicilian temples; the eastern front had relief metopes, partly preserved. A huge, artificial terrace in front of the temple, framed by a stoa in the eastern end, was built as part of the same programme.
