English: "In the southeast of the Ancient Agora in an area with impressive rock foundations, looms the "Eleusinion in the City" ("εν άστει Ελευσίνιο") between the Panathenaic Way on the west and the two branches of the "Street of the Tripods" on the north and south. It was a shrine sacred to the mystery religion of the goddess Demeter and Persephone along with their mortal counterpart Triptolemos. These Eleusinian deities were worshipped here already in the 6th century B.C., in an open-air shrine surrounded by a wall. In the second quarter of the 5th century B.C. the shrine received a small rectangular temple oriented north-south. Of this Ionic tetrastyle amphiprostyle temple, with an inner shrine and shallow pronaos are preserved only the groundwork of three sides. In the 4th century B.C. the need to reinforce the embankment of the temple led to the construction of a strong retaining wall. The area north of the temple embarkment, which is at a lower level acquired a number of rooms in the early Roman period, which have been interpreted as shops or as storerooms for grain for the temple. In the corner at the east are round bases for dedications of the Hellenistic and early Roman periods. In the reorganization of the shrine, in the 2nd century B.C., a colonnade and a propylon were built south of the temple. On the south and farther uphill from the Eleusinian stand a section of the Hadrianic aqueduct (2nd century A.D.) and remains of a round building, ca. 8 meters in diameter, built in the 2nd century B.C., and thought to be a shrine of Pluto."
