The Acropolis of Athens, seen from Philopappou hill

The Acropolis of Athens (Greek: Ακρόπολη Αθηνών) is an ancient citadel located on a high rocky outcrop above the city of Athens and containing the remains of several ancient buildings of great architectural and historic significance, the most famous being the Parthenon. The word acropolis comes from the Greek words ἄκρον (akron, "edge, extremity") and πόλις (polis, "city"). Although there are many other acropoleis in Greece, the significance of the Acropolis of Athens is such that it is commonly known as "The Acropolis" without qualification.
