2nd period (1640-1833)
The monuments of the Acropolis, and mainly the Parthenon, used to stand almost intact since the antiquity. In the 17th century, however, two destructions took place. In 1640 a lightning caused an explosion in the Propylaea where gunpowder was stored. Parthenon became the next gunpowder magazine. During the siege by the Venetians, under the command of the future Doge Francesco Morosini, a canon shell fell in the Parthenon and caused a huge explosion (night of September 26, 1687). The Turks immediately afterwards, built a smaller mosque between the ruins of the Parthenon, which was demolished in 1844 along with all of the houses. The big medieval tower in the Propylaea was also demolished in 1875.
Between 1801 and 1812, Thomas Bruce, 7th Earl of Elgin removed more than half of the sculptures of the Parthenon, parts of the Erechtheion (including a caryatid), along with many other antiquities, causing major damage to the monuments, and took them to England. The removal of the sculptures immediately caused great dispute which continues today. Elgin sold his collection to the British Museum in London in 1816, where it still remains.
During the Greek War of Independence, the city of Athens was occupied by the Greek forces for the first time on April 25, 1821 and the Turks of the Acropolis surrendered on June 9, 1822, after many skirmishes. During that siege, the Turks on the Acropolis dismantled large parts of the remaining Parthenon walls to remove the lead clamps which held the blocks together, in order to produce ammunition.
In 1826-1827 the city was extensively destroyed during the siege and bombing by the Turkish General Kutahi Pasha, who managed to recapture it. Athens was officially liberated on March 31, 1833, with the departure of the Turkish guard from the Acropolis. Rebuilding plans begun immediately and on September 18, 1834, Athens was declared the capital of Greece.
