On the rocky hill of the Acropolis, which dominates the center of modern Athens, stood the most emblematic and magnificent sanctuary of the ancient city, dedicated primarily to its patron goddess, Athena. This sanctuary is associated with the most important myths of ancient Athens, the major religious festivals, the city's oldest cults, and some of the most critical events in its history. The monuments of the Acropolis, harmoniously connected with the natural environment, reflect the ancient, unique Greek architecture, expressing pioneering associations of rhythms and trends in classical art, which influenced intellectual and artistic creation for many centuries to come. The Acropolis of the 5th century B.C. perfectly represents Athens's grandeur, power, and wealth in its greatest heyday, the 'golden age' of Pericles. In the middle of the 5th century B.C., the headquarters of the Athenian Alliance was moved to the Acropolis, and Athens was the most important center of the intellectual world; a grand building program was implemented on the initiative of Pericles, which lasted throughout the second half of the 5th century B.C. Many people, Athenians and foreigners, free and slaves, worked for a daily wage of one drachma. It was then that the most important monuments, like the Parthenon, the Erechtheion, the Propylaia, and the Temple of Athena Nike that visitors can see today were built under the supervision of the most skilled artists, architects, and sculptors. Athena was worshipped in all her attributes related to the city: Polyas, the city's patroness, as the Virgin; Pallas; Promachus, the goddess of war; Erganes, the goddess of manual labor; and Nike. It is characteristic that, while other Greek sanctuaries were severely looted and destroyed during the Roman period, the Acropolis retained its old glory and continued to gather the rich offerings of the faithful. In the following centuries, the monuments of the Acropolis had intense damage from natural causes or human intervention. With Christianity, the monuments were turned into Christian churches. The Parthenon became a Christian church dedicated to the Virgin Mary, and by the end of the 11th century, it was the metropolis of Athens. The Erechtheion was turned into a church of the Saviour, the temple of Athena Nike into a chapel, and the Propylaea into a bishop's residence. The rock of the Acropolis was the fortress of the city. During the Frankish occupation (1204-1456), the Propylaea was converted into a palace for the Frankish rulers, while during the Turkish occupation (1456-1833), the Acropolis again became the fortress of the city, where the Turkish garrison chief resided. In 1687, during the Second Venetian-Turkish War, the hill was surrounded by F. Morosini. On September 26, 1687, a Venetian bomb blew up the Parthenon, which had been turned partly into a storage place for gunpowder. The monuments were severely destroyed between 1801 and 1802. Lord Elgin looted the Parthenon's sculptural decoration, removed sculptures from the Temples of Athena Nike and the Erechtheion, and compromised structural members of the temple. The Acropolis finally came under Greek rule in 1822, and Odysseus Androutsos was appointed its first fortress commander. After the liberation, the new Greek state took care of the Acropolis's monuments. The first excavations on the hill took place between 1835 and 1837.
