The Acropolis of Athens is an ancient citadel located on a rocky outcrop above the city of Athens and contains the remains of several ancient buildings of great architectural and historic significance, the most famous being the Parthenon. The word acropolis is from the Greek words ἄκρον (akron, "highest point, extremity") and πόλις (polis, "city"). Although the term acropolis is generic and 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. During ancient times it was known also more properly as Cecropia, after the legendary serpent-man, Cecrops, the supposed first Athenian king.
While there is evidence that the hill was inhabited as far back as the fourth millennium BC, it was Pericles (c. 495–429 BC) in the fifth century BC who coordinated the construction of the site's most important present remains including the Parthenon, the Propylaea, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were seriously damaged during the 1687 siege by the Venetians during the Morean War when gunpowder being stored in the Parthenon by the Ottomans was hit by a cannonball and exploded.
