The Athenian Metroon was located on the west side of the city's Agora, in the Old Bouleuterion which formerly housed the city council. At the end of the 5th century BC, the New Bouleuterion was built and the council's former home converted into a temple to Cybele. Supposedly, the Athenians had killed one of her wandering priests when he attempted to introduce her cult; the plague which then visited the city was dealt with by honoring her. (The account may, however, have been a later invention, as the earliest source is from the 4th century AD.) The Metroon continued to serve a public function, housing the official archives of the city.
