Stageira (Greek: Στάγειρα; more properly Stagira Στάγιρα; also fem.Stagiros Στάγιρος or Stageiros Στάγειρος) was an ancient Greek city on the Chalcidicepeninsula and is chiefly known for being the birthplace of Aristotle. The city lies a few kilometres north of the present-day village of Stagira, close to the city now called Olympias.
Philip II of Macedon later had more success, occupying and destroying the city. As payment for Aristotle's tutoring of his son, who became Alexander the Great, Philip later rebuilt the city and resettled the old city's inhabitants, who had been enslaved, there. Many new structures were built at this time, including an aqueduct, two shrines to Demeter and many houses.
