Acropolis

An acropolis is a settlement, especially a citadel, built upon an area of elevated ground—frequently a hill with precipitous sides, chosen for purposes of defense. In many parts of the world, acropoleis became the nuclei of large cities of classical antiquity, such as ancient Rome, and for this reason they are sometimes prominent landmarks in modern cities with ancient pasts, such as modern Rome.

Use in antiquity
The word acropolis literally means in Greek “upper city,” and though associated primarily with the Greek cities Athens, Argos ( with Larissa), Thebes (with Cadmea), and Corinth (with its Acrocorinth), may be applied generically to all such citadels, including Rome, Jerusalem, Celtic Bratislava, many in Asia Minor, or even Castle Rock in Edinburgh. An example in Ireland is the Rock of Cashel. Acropolis is also the term used by archaeologists and historians for the urban Castro culture settlements located in Northwestern Iberian hilltops.

The most famous example is the Acropolis of Athens, which, by reason of its historical associations and the several famous buildings erected upon it (most notably the Parthenon), is known without qualification as the Acropolis. Although originating in the mainland of Greece, use of the acropolis model quickly spread to Greek colonies such as the Dorian Lato on Crete during the Archaic Period.

Metaphorical use in modern times
Because of its classical Hellenistic style, the ruins of Mission San Juan Capistrano’s Great Stone Church in California, United States has been called the “American Acropolis”.

Other parts of the world developed other names for the high citadel or alcázar, which often reinforced a naturally strong site. In Central Italy, many small rural communes still cluster at the base of a fortified habitation known as La Rocca of the commune.

The term acropolis is also used to describe the central complex of overlapping structures, such as plazas and pyramids, in many Maya cities, including Tikal and Copán.

Acropolis of Athens
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 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 Propylaia, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were damaged seriously during the 1687 siege by the Venetians during the Morean War when gunpowder being stored in the Parthenon was hit by a cannonball and exploded.
