Lechaeum or Lechaion (Ancient Greek: τὸ Λεχαῖον), also called Lecheae[1] and Lecheum,[2] was the port in ancient Corinthia on the Corinthian Gulf connected with the city of Corinth by means of the Long Walls, 12 stadia in length.
[7][8] The flat country between Corinth and Lechaeum is composed only of the sand washed up by the sea; and the port must have been originally artificial,[9] though it was no doubt rendered both spacious and convenient by the wealthy Corinthians.
The proximity of Lechaeum to Corinth prevented it from becoming an important town like Piraeus.
The only public buildings in the place mentioned by Pausanias, who visited in the 2nd century, was a temple of Poseidon,[10] who is hence called Lechaeus by Callimachus.
[11] The temple of the Olympian Zeus was probably situated upon the low ground between Corinth and the shore of Lechaeum.
