The Acropolis of Athens (Ancient Greek: Ἀκρόπολις; Modern Greek: Ακρόπολη Αθηνών) is an ancient citadel located on a high 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 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.
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 buildings including the Parthenon, the Propylaia, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were seriously damaged during the 1687 siege by the Venetians in the Morean War when the Parthenon was being used for gunpowder storage and was hit by a cannonball. The Acropolis was formally proclaimed as the preeminent monument on the European Cultural Heritage list of monuments on 26 March 2007.
The entrance to the Acropolis was a monumental gateway called the Propylaea. To the south of the entrance is the tiny Temple of Athena Nike. At the centre of the Acropolis is the Parthenon or Temple of Athena Parthenos (Athena the Virgin). East of the entrance and north of the Parthenon is the temple known as the Erechtheum. South of the platform that forms the top of the Acropolis there are also the remains of an outdoor theatre called Theatre of Dionysus. A few hundred metres away, there is the now partially reconstructed Theatre of Herodes Atticus. All the valuable ancient artifacts are situated in the Acropolis Museum, which resides on the southern slope of the same rock, 280 metres from the Parthenon.
The Acropolis Restoration Project:
The Project began in 1975 and is now nearing completion. The aim of the restoration was to reverse the decay of centuries of attrition, pollution, destruction by acts of war, and misguided past restorations. The project included collection and identification of all stone fragments, even small ones, from the Acropolis and its slopes and the attempt was made to restore as much as possible using reassembled original material (Anastylosis) - with new marble from Mount Penteli used sparingly. All restoration was made using titanium dowels and is designed to be completely reversible, in case future experts decide to change things. A combination of cutting-edge modern technology and extensive research and reinvention of ancient techniques were used.
The Parthenon colonnades, largely destroyed by Venetian bombardment in the 17th century, were restored, with many wrongly assembled columns now properly placed. The roof and floor of the Propylaea were partly restored, with sections of the roof made of new marble and decorated with blue and gold inserts, as in the original. Restoration of the Temple of Athena Nike was completed in 2010. A total of 2,675 tons of architectural members were restored, with 686 stones reassembled from fragments of the originals, 905 patched with new marble, and 186 parts made entirely of new marble. A total of 530 cubic meters of new Pentelic marble were used.
