Muros Largos
Lechaeum or Lechaion (), also called Lecheae and Lecheum, 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. The Long Walls ran nearly due north, so that the wall on the right hand was called the eastern, and the one on the left hand the western or Sicyonian. The space between them must have been considerable; since there was sufficient space for an army to be drawn up for battle. Indeed, the area was the scene of battles between Sparta and Athens in 391 BCE, leaving Spartans in command of Lechaeum, which they garrisoned with their troops (see Battle of Lechaeum).
