The area extends approximately from Via Salaria and the end of Viale Regina Margherita, to the slope descending towards the Tiber and the Museum of Modern Art, found on the Viale delle Belle Arti. The other two sides are approximately delineated by Villa Borghese and Villa Ada. In the 19th century, Viale Regina Margherita was a tree-lined avenue that led from the neighborhood of the San Lorenzo district to the fields of Monti Parioli.
Principal arteries of the area include:
Parioli began as an upper-class neighbourhood and during the Fascist period was the residence of many high-ranking party and state functionaries. Urbanization was completed in the 1950s. Today, Parioli is synonymous with wealthy and expensive living. It is mainly a residential area, although a number of foreign embassies are located there.
The inhabitants of Parioli are called Pariolini, a typical pariolino could be seen wearing smart sportswear, driving a Mini Cooper, attending fine bars (e.g. I Tre Frocci), being right wing on the verge of fascist, and supporting SS Lazio. The stereotype is extended to other fine fashioned Roman youth. In the past it meant an exclusive, gilded aura and a strong conservative and class statement mentality, expressed in a far Right wing political view.
