Israel/Palestine

The Siege of Jerusalem in the year 70 was the decisive event of the First Jewish–Roman War. The Roman army, led by the future Emperor Titus, with Tiberius Julius Alexander as his second-in-command, besieged and conquered the city of Jerusalem, which had been occupied by its Jewish defenders in 66.

The siege ended with the sacking of the city and the destruction of its famous Second Temple. The destruction of both the first and second temples is still mourned annually as the Jewish fast Tisha B'Av. The Arch of Titus, celebrating the Roman sack of Jerusalem and the Temple, still stands in Rome.

Josephus claims that 1.1 million people were killed during the siege, of which a majority were Jewish, and that 97,000 were captured and enslaved, including Simon bar Giora and John of Giscala.

"The slaughter within was even more dreadful than the spectacle from without. Men and women, old and young, insurgents and priests, those who fought and those who entreated mercy, were hewn down in indiscriminate carnage. The number of the slain exceeded that of the slayers. The legionaries had to clamber over heaps of dead to carry on the work of extermination."

Kinda like how the Great Synagogue of Warsaw "stopped being a synagogue".
