During the 17th Century Venetian expedition against the Turks who had occupied Athens, a French artillery officer serving with the Venetians decided to show his marksmanship by lobbing a shell through the roof of the Parthenon. It hit a Turkish gunpowder magazine inside and collapsed the roof and some walls, so he would be a contender.
A second raid was British collector Lord Elgin who, with Turkish permission, took much of the statuary, most of which was lying untended on the ground, back to England. At least that was properly stored and displayed, and is in reasonable condition, called the Elgin Marbles.
The other enemy was Greek neglect. They allowed the buildings and statuary to deteriorate and through the middle of the 20th Century, the acid rain generated by the city ate away the marble statues of the Caryatids and facades. In a later belated recovery effort the statues were moved into store rooms, and then replaced by copies which had to be made from the Elgin Marbles.
Pick which you think was the biggest villain. Elgin at least acted constuctively and the British Museum carefully protected them. The Frenchman and the Greek governmant run neck and neck.
