The Acropolis of Athens is a limestone hill rising 150 m above the city, topped by the remains of several ancient buildings of great architectural and historic significance, most notably the Parthenon. The flat-topped rock covers about 30,000 square meters and has been continuously occupied since at least the 4th millennium BC. The Parthenon, built between 447 and 432 BC under Pericles, measures 69.5 m by 30.9 m and originally contained a 12 m tall gold-and-ivory statue of Athena by Phidias.
