Mantineia — A settlement in Peloponnese
Mantineia was a city in ancient Arcadia, Greece that was the site of two significant battles in Classical Greek history.

It emerged from the amalgamation of several neighbouring villages around 500BC. It's patron god was Poseidon. It was a large city with many temples. One very important was the temple of Artemis Hymnia, just on the north of the city. There, Diotima, Socrates philosophy influencer, probably was a priestess. Near the city was the dam of Mantineia, a wonder of ancient technology.

Macedonian king Antigonus III Doson sacked the city at 223BC. Antigonos handed the city to the Achaeans, which colonized it, under Aratos, and renamed the city to Antigonia. The name Mantineia was restored by Hadrian.
