Decelēa (Dekeleia), an Attic deme north-east of Athens near the pass east across Mount Parnes. It was about 22 km. (14 miles) from Athens and visible from there; ships entering Piraeus were in its view. Its occupation by the Spartans in 413 BC, during the Peloponnesian War, at the suggestion of the Athenian Alcibiades, put a stranglehold on Athens for the rest of the war. The term ‘Decelean War’ is sometimes used to describe the last period of the Peloponnesian War, from 413 to 404.
