Palazzi dell'INA e dell'INPS (INA-INPS Buildings), Rome

Situated on the United Nations Square ("Piazzale delle Nazioni Unite"), two buildings stand side by side, bearing a resemblance yet showcasing slight differences. To the left is the Palazzo dell'INPS, while on the right stands the Palazzo dell'INA. Both structures feature a semi-circular design, influenced by the classical Roman Markets of Trajan, as envisioned by the architects Muzio-Paniconi-Pediconi. Their distinctive shape was originally intended to be part of an Imperial Gate, intended to welcome visitors to the 1942 World's Fair. These "different twins" are constructed from reinforced concrete and adorned with marble sourced from the Apuan Alps.

Notably, each building is adorned with a pair of bas-reliefs, crafted by different artists but united in their portrayal of a female figure larger than the rest. This symbolizes the strength and unity of the fascist regime that spearheaded the construction of the EUR district.

The INPS building showcases "The Maritime Republics" by Mirko Basaldella and "Rome against Carthage" by Giuseppe Mazzullo. Furthermore, this building, which has always served as the national headquarters of the National Social Security Institute, features additional bas-reliefs at its entrance, created by Antonio Cocchioni. As for the INA building, it features "The Conquests of the Seas" by Oddo Aliventi and "The Fascist Empire" by Quirino Ruggeri. Worth noting also are the grand vaulted colonnades present in both buildings.
