Megalopoli is set in the heart of a fertile valley and is the seat of the Municipality bearing its name, and the capital of the province. In antiquity, this was the location of the ancient Megali Poli established shortly after the victory of the general Epaminondas from Thebes over Spartans in Lefktra (371BC). The town soon became the largest one in Arcadia. However, the Spartans ruined it in 222BC. Megalopolis is 74km from Tripoli and has a population of approximately 5,000.
