[6] Upon a very conspicuous peaked height upon the isthmus of Ichthys are the ruins of a castle of the Middle Ages, called Pontikokastro, built upon the remains of the Hellenic walls of Pheia.

[4] On either side of Ichthys are two harbours; the northern one, which is a small creek, was the port of Pheia; the southern one is the broad bay of Katakolo, which is now much frequented, but was too open and exposed for ancient navigation.

The position of these harbours explains the narrative of Thucydides, who relates that in the first year of the Peloponnesian War (431 BCE), the Athenian fleet, having sailed from Methone in Messenia, landed at Pheia (that is, in the bay of Katakolo), and laid waste the country; but a storm having arisen, they sailed round the promontory Ichthys into the harbour of Pheia.

In 1973 the Hellenic Institute of Marine Archaeology made a survey in the bay of Agios Andreas near Katakolo, and found the remains of the town at a depth of 5 metres (16 ft) below sea level.

[10] Two cycladic marble figures from the Bronze Age were found on the headland, as well as finds of tombs and remains of Roman buildings on Tigani island.
