Across the East-West street there is a second sacred area, north of the preceding. There, to the south of Temple C is a Shrine 17.65 metres long and 5.5 metres wide which dates from 580 to 570 BC and has the archaic form of the "Megaron", perhaps intended to hold votive offerings. Lacking a pronaos, the entrance at the eastern end passed directly into the naos (at the centre of which there are two bases for the wooden columns which held up the roof). At the back there was a square adyton, to which a third space was added in a later period. The Shrine was perhaps dedicated to Demeter Thesmophoros.
