What were the Turks storing in Parthenon?

During the Ottoman period, the Parthenon was used as a storage facility for ammunition and gunpowder. This repurposing of the ancient temple occurred after the Ottomans converted it into a mosque and later a military barracks. The storage of explosive materials ultimately led to significant damage to the structure, especially during a Venetian bombardment in 1687, which caused a large explosion and further deterioration of the monument.
