 The part of Della Vittoria Suburb overlooking Piazza Nostra Signora di Guadalupe is called Monte Mario Alto ("High Monte Mario") and develops close to Colle Sant'Agata, where, in the 1920s, a cooperative of post and telegraph workers built the first settlement.Other popular housing units were added in the 1930s, while the full edification was completed between the 1960s and the 1980s.Monte Mario is also historically linked to the complex of the former Manicomio Santa Maria della Pietà, one of the largest and oldest mental health hospital in Europe.
