The Acropolis of Athens is an ancient citadel built on a rocky hill overlooking the city of Athens. The Athenian Acropolis is a giant ensemble of buildings, with the Parthenon being the famous one. To this day, only several significant ancient buildings remain of the citadel. Pericles, a famous historical figure, coordinated the construction of the buildings that are considered to be the most important ones, like the Parthenon, the Propylaea, the Erechteion and the Temple of Athena Nike. The Parthenon and the other buildings were seriously damaged during the 1687 siege by the Venetians, as they hit the gunpowder storage at the Parthenon with a cannonball and it exploded.
