Map of ancient Chalcidice, showing peninsula of Pallene and Potidaea

Potidaea (/ˌpɒtɪˈdə/; Greek: Ποτίδαια, Potidaia) was a colony founded by the Corinthians around 600 BC in the narrowest point of the peninsula of Pallene, the westernmost of three peninsulas at the southern end of Chalcidice in northern Greece.[1]

While besieged by the Persians in 479 BC, the town was saved by the earliest recorded tsunami in history.[2] Herodotus reports how the Persian attackers who tried to exploit an unusual retreat of the water were suddenly surprised by "a great flood-tide, higher, as the people of the place say, than any one of the many that had been before".[3] In 2012 researchers from Aachen University announced that they had discovered evidence that supported the account of Herodotus and that the area should be included among Greek regions prone to tsunamis.[4]

During the time of the Delian League, conflicts occurred between Athens and Corinth. However, the Corinthians still sent a supreme magistrate each year. Potidaea was inevitably involved in all of the conflicts between Athens and Corinth. The people revolted against the Athenians in 432 BC, and it was besieged at the beginning of the Peloponnesian War and taken in the Battle of Potidaea in 430 BC.[5]

The Athenians retook the city in 363 BC, but in 356 BC Potidaea fell into the hands of Philip II of Macedon. Potidaea was destroyed and its territory handed to the Olynthians. Cassander built a city on the same site which was named Cassandreia. It was probably at this time that the canal which still exists today was dug through the sandy soil at the narrowest part of the isthmus, perhaps with the aim if making the city a naval base. In 43 BC a Roman colony was settled by the proconsul of Macedonia, which in 30 BC was resettled by August and took the official name Colonia Iulia Augusta Cassandrensis.[6]

The modern settlement of Nea Poteidaia, built for refugees from Asia Minor after the First World War, is situated near this ancient site.

In popular culture, the fictional character Gabrielle from the TV series Xena: Warrior Princess was described as being from Potidaea.
