In 1687, the Parthenon was extensively damaged in the greatest catastrophe to befall it in its long history. As part of the Morean War (1684–1699), the Venetians sent an expedition led by Francesco Morosini to attack Athens and capture the Acropolis. The Ottoman Turks fortified the Acropolis and used the Parthenon as a gunpowder magazine – despite having been forewarned of the dangers of this use by the 1656 explosion that severely damaged the Propylaea – and as a shelter for members of the local Turkish community.
