The villa is located along a side street of Via Salaria.
Over the following centuries, probably due to the difficulties to defend the hill by military force, people left the place and the area remained uninhabited. Only the bridge on the Anio wasn’t abandoned and, over the years, it was turned into a checkpoint and customs house.
The Secession of the Plebs in 494 B.C.
During the Secession of the Plebs, rioters retreated to Mons Sacer (Montesacrco, the Sacred Mount); it can be considered the first strike in the history. Menenius Agrippa, a patrician consul, convinced them to return thanks to his famous apologue of the belly and the limbs. The rioters abode for days, refusing to work,' till they were granted a number of privileges, including the right to elect tribunes and aediles of the plebs and to appoint the Concilium Plebis (known in English as the Plebeian Council or People's Assembly) through which the plebeians (commoners) could, inter alia, elect magistrates and pass laws (concilia plebis or plebiscita) that would only apply to them.
As a reminder and warning of the occurrence, on the top of the hill the Plebs erected an altar dedicated to Jupiter Terrificus (frightful). Maybe the name “Montesacro” (The Sacred Mount) comes also from this event.
