The Long Walls can be distinguished beginning from the summit of Acrocorinth and leading to the artificial harbour of Leheo or Lechaion. This is where Lechaion road began, in ancient times a paved road with shops, temples and important edifices, as well as different markets or emporia. To the north of the agora or market lies the significant Doric temple of Apollo, dating from the 6th century BC with restorations undertaken in the 1st century AD. There are also ruins of a theatre from the 4the century BC and a Roman Odeon. Visit the museum on the site with mosaic floors, pottery from the Corinthian and Mycenaean eras, sphinxes of terra cotta, reliefs, roman heads and other important finds.
Note that Acrocorinth or Acrokorinthos – which is 575 metres high – is considered the oldest and largest fort in the Peloponnese, with evidence of Frankish, Byzantine, Venetian and Ottoman alterations and additions. In ancient times there were many temples and shrines on the summit, overshadowed by the Temple of Aphrodite. Also noteworthy further down is the Pirene or Peirene Spring.
