Parthenon

On September 26, 1687, the Parthenon on the Acropolis in Athens was damaged by a shell as the Venetian army attacked the Turks. An excerpt from the article:

"Later History
In its new form the building survived for another thousand years. Then in 1458 the occupying Turks converted the building into a mosque and so added a minaret in the southwest corner. In 1674 a visiting artist (possibly one Jacques Carey) took drawings of much of the sculpture, an extremely fortuitous action considering the disaster that was about to strike.

In 1687 the Venetian army under General Francesco Morosini besieged the acropolis which had been occupied by Turkish forces who used the Parthenon as a powder magazine. On the 26th of September a direct hit from a Venetian shell ignited the magazine and the massive explosion ripped apart the Parthenon. All the interior walls except the east side were blown out, columns collapsed on the north and south sides, carrying with them half of the metopes. If that wasn't enough, Morosini further damaged the central figures of the west pediment in an unsuccessful attempt to loot them and smashed to pieces the horses from the west pediment when his lifting tackle collapsed. From the rubble, the Turks cleared a space and built a smaller mosque, but no attempt was made to gather together the fallen ruins or protect them from any casual artefact robber. Frequently, in the 18th century, foreign tourists helped themselves to a souvenir from the celebrated ruin."
