Achilleius or Achilleios (Ancient Greek: Ἀχίλλειος), also known as Achilleius Portus or Achilleios limen (Ἀχίλλειος λιμὴν), was a harbour of ancient Laconia.
The Periplus of Pseudo-Scylax places it between Methone and Psamathus, inside Laconia.
[1] Pausanias places it near Cape Matapan and the port of Psamathus, at about 150 stadia from Teuthrone.
He says that at the end of Cape Matapan there was a temple in the shape of a cave and a statue of Poseidon.
