The Palazzo delle Poste at Piazza Bologna in Rome was designed by architects Mario Ridolfi and Mario dell’Arco and completed in 1935. Situated in the Nomentano district between viale delle Provincie and viale Ventuno Aprile, the building represents the rationalist idiom that would define Ridolfi’s career.
Piazza Bologna itself developed in the early twentieth century as a residential area for the upper-middle class, characterized by four-storey villas with refined architectural detailing. The fascist period consolidated the area’s radial street plan, established by the 1909 master plan, while transforming its architectural character through the introduction of apartment buildings. The postal palace emerged from this transitional moment, marking a shift toward institutional and residential modernism in the quarter.
