Following to the fall of the Roman Empire, the ancient patrician villas were replaced by the medieval farmsteads, resulting in the depopulation of the area. However, the zone was constantly controlled, as the Ponte Nomentano was a relevant outpost and an important crossing point toward the northern Latium. Traditionally, Ponte Nomentano is considered the place where Pope Leo III met Charlemagne in 800. Because of the distance from the city, the territory became a place for jaunts and trips to the countryside, up to the beginning of the 19th century. According to the tradition, it was during a trip in Monte Sacro countryside in 1805 that Simon Bolivar took the oath to free the Latin American people, after his mentor and friend Simon Rodriguez told him that the Roman plebs made camp on the Mons Sacer following to its secession from the city. Construction started on the area in the 1920s, when architect Gustavo Giovannoni planned and built a new borough, inspired by the principles of the Garden city movement. Piazza Sempione is the spectacular entry to the quarter, surrounded by the edifices that were planned by Giovannoni himself and by Innocenzo Sabbatini. The quarter was called Città Giardino Aniene, and was officially renamed Monte Sacro in 1924. The commitment of the locals to the Resistenza during the Nazi occupation has been very remarkable, and two residents of Monte Sacro, the partisans Ferdinando Agnini and Orlando Orlandi Posti, were killed in the Ardeatine massacre. The whole neighborhood, particularly Piazza Sempione and Viale Jonio, is the setting of Beppe Fenoglio's novel Primavera di bellezza, set in the resistance years. The "garden city" endured for just 30 years, since in the 1950s residential buildings took the place of cottages and detached houses. Further expansions took place in the 1960s, in the areas of Tufello and Conca d'Oro, while in the second half of the 1960s, in the area of Talenti, the new quarter of Monte Sacro Alto took shape.
