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 Pentelicus 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 during 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. In 2021, the addition of new reinforced concrete paths to the site to improve accessibility caused controversy among archaeologists. Cultural significance Every four years, the Athenians had a festival called the Great Panathenaea that rivaled the Olympic Games in popularity. During the festival, a procession (believed to be depicted on the Parthenon frieze) traveled through the city via the Panathenaic Way and culminated on the Acropolis. There, a new robe of woven wool (peplos) was placed on either the statue of Athena Polias in the Erechtheum (during the annual Lesser Panathenaea) or the statue of Athena Parthenos in the Parthenon (during the Great Panathenaea, held every four years). Within the later tradition of Western Civilization and classical revival, the Acropolis, from at least the mid-18th century on, has often been invoked as a critical symbol of the Greek legacy and of the glories of Classical Greece. Most of the artifacts from the temple are housed today in the Acropolis Museum at the foot of
