A 7th century BC Aqueduct

Delos was a sanctuary since the Mycenaean period (circa 1400 BC) and became organized in the 7th century BC. The Odyssey, written about 700 BC, refers to Delos as a famous religious center of the Ionians. It grew to about 30,000 inhabitants and was destroyed in 88 BC by Mithridates, King of Pontus. During this time, the people of Delos built aqueducts that brought fresh water to their houses.
