The Academy was a large enclosure of ground about six stadia (a total of between a kilometer and a half mile) outside of Athens proper. One story is that the name of the Academy comes from the ancient hero, Academus; still another story is that the name came from a supposed former owner of the plot of land, an Athenian citizen whose name was (also) Academus; while yet another account is that it was named after a member of the army of Castor and Pollux, an Arcadian named Echedemus. The Academy operated until it was destroyed by Lucius Cornelius Sulla in 84 BC. Many intellectuals were schooled in the Academy, the most prominent one being Aristotle.
