 Parioli began as an upper-class district in the first years of 20th century, with the construction of Viale Parioli, sponsored by two major landowners of the area, Filonardi and Giorgi.In their project, the new thoroughfare is conceived as a "city promenade", a tree-lined street with a lateral riding track and flanked by elegant houses.Viale Parioli was then extended up to Viale Liegi, and two more boulevards were built, Viale Tiziano and Viale Maresciallo Pilsudski
