Modern Description: The fertile plain that was under the jurisdiction of Eleusis and through which the Sacred Way (Iera Odos, Ἱåñὰ Ὁäὸò) passed, was called the Thriasian plain after the nearby deme of Thria. According to tradition it was here that agriculture was first practised, under the guidance of the goddess Demeter. On the W side of the plain are the ruins of two frontier forts of Attica (5th-4th century BC), with circular towers at the sites of Plakoto and Palaiokastro. Other sights of interest are the brackish sacred lakes of Rheitoi (modern Lake Koumoundourou), via which the procession of the Eleusinian Mysteries passed, and the impressive remains of a stone bridge (l. 50 m) over the Eleusinian Kephisos (modern Sarandaporos) in the locality Kalo Pigadi. It was originally constructed in the late 4th century BC, but the extant monumental form is dated to the reign of Emperor Hadrian (AD 124/5).
