|Summary:||Gate building; northeastern gate to the Sanctuary of Demeter and Kore.|
|Date:||ca. 170 AD - ca. 180 AD|
Doric hexastyle amphiprostyle building approached by 6 steps on the east. Continuing from the east, an Ionic inner colonnade of 6 columns divided the building into 3 aisles. Beyond, was a cross wall pierced by 5 doorways. The central passage between the columns and through the doors was wider than the side passages.
Probably built by Marcus Aurelius on the same site as an earlier gate from the time of Kimon. It copied the central form of the Mnesiklean Propylaia in Athens.
