[Greece] Acropolis of Athens


Acropolis of Athens
The Acropolis of Athens or Citadel of Athens is the best known acropolis (Gr. akros, akron,edge, extremity + polis, city, pl. acropoleis) in the world. Although there are many other acropolis in Greece, the significance of the Acropolis of Athens is such that it is commonly known as The Acropolis without qualification. The Acropolis was formally proclaimed as the preeminent monument on the European Cultural Heritage list of monuments on 26 March 2007.The Acropolis is a flat-topped rock that rises 150 m (490 ft) above sea
level in the city of Athens, with a surface area of about 3 hectares. It was also known as Cecropia, after the legendary serpent-man, Cecrops, the first Athenian king.

Acropolis of Athens
While the earliest artifacts date to the Middle Neolithic era, there have been documented habitations in Attica from the Early Neolithic (6th millennium BC). There is little doubt that a Mycenaean megaron stood upon the hill during the late Bronze Age. Nothing of this megaron survives except, probably, a single limestone column-base and pieces of several sandstone steps. Soon after the palace was constructed, a Cyclopean massive circuit wall was built, 760 meters long, up to 10 meters high, and ranging from 3.5 to 6 meters thick. This wall would serve as the main defense for the acropolis until the 5th century.The wall consisted of two parapets built with large stone blocks and cemented with an earth mortar called emplekton (Greek: ἔμπλεκτον). The wall follows typical Mycenaean convention in that it followed the natural contour of the terrain and its gate was arranged obliquely, with a parapet and tower overhanging the incomers' right-hand side, thus facilitating defense. There were two lesser approaches up the hill on its north side, consisting of steep, narrow flights of steps cut in the rock. Homer is assumed to refer to this fortification when he mentions the "strong-built House of Erechtheus" (Odyssey 7.81). At some point before the 13th century an earthquake caused a fissure near the northeastern edge of the acropolis. This fissure extended some thirty five meters to a bed of soft marl in which a well was dug. An elaborate set of stairs was built and the well was used as a protected source of drinking water during some portion of the Mycenaean period, as it was invaluable in times of siege.

There is no conclusive evidence for the existence of a Mycenean palace on top of the Athenian Acropolis. However, if there was such a palace, it seems to have been transplanted by later building activity on the Acropolis. Not much is known as to the architectural appearance of the Acropolis until the archaic era. In the 7th and the 6th centuries BC, the site was taken over by Kylon during the failed Kylonian revolt, and twice by Pisistratus: all attempts directed at seizing political power by coups d' etat. Nevertheless, it seems that a nine-gate wall, the Enneapylon, had been built around the biggest water spring, the "Clepsydra", at the northwestern foot.

Acropolis of AthensThe Acropolis Restoration 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 - 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. The temple of Athena Nike is the only edifice still unfinished, pending proper reassembly of its parts, all of which survive practically intact.

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.
