The site of the arx of the ancient town was probably on the hill on which lies the contemporary Villa Spada, though no traces of early buildings or defences are to be seen; pre-Roman tombs are in the cliffs to the north.Sextus Tarquinius, whose rape of Lucretia had triggered the overthrow of the monarchy (if he was not assassinated at Gabii), convinced the Sabines to go to war against Rome, arguing that previous treaties had been annulled by the expulsion of the kings.The city was taken only a few days later: the Romans assembled their prisoners and executing the senior officers before them (whipped by the rods and beheaded by the axe of the fasces, a standard punishment for treason), let the rest go with a stern warning.In 27 AD, an apparently cheaply built wooden amphitheater constructed by an entrepreneur named Atilius collapsed in Fidenae, resulting in what was said to be the worst stadium disaster in history, with at least 20,000 killed and many more injured out of the total audience of 50,000.[6][7] The emperor Tiberius had banned gladiatorial games, and when the prohibition was lifted, the public had flocked to the earliest events, so a large crowd was present when the stadium collapsed.
