The headquarters of Italy’s national social security institute stands on Piazzale delle Nazioni Unite in the EUR district, one of two symmetrical exedra-fronted blocks that frame the entrance to the quarter designed for the 1942 world fair.

History
The building was conceived as part of the E42, the Esposizione Universale planned for 1942 but never held because of the Second World War. A project was assigned between 1938 and 1939 to Giovanni Muzio, Mario Paniconi and Giulio Pediconi. The structure was intended to house the Mostra della Previdenza and was financed by the Istituto Nazionale della Previdenza Sociale, which has occupied it ever since. Between 1957 and 1967 Paniconi and Pediconi completed a new wing on Via Ciro il Grande.
What you see
The palace has a curved exedra plan that mirrors the former INA building on the opposite side of the square, a composition inspired by the Markets of Trajan. It is built of reinforced concrete clad in marble from the Apuan Alps. On the upper facade two large rectangular relief panels: one shows a central winged figure with haloed saints and soldiers, and at its base a lion holding a tablet and a dragon; the second has a robed female figure at the centre with armed soldiers raising shields and spears and fallen figures along the lower edge. Documents name two sculptures of 1941: Giuseppe Mazzullo’s Roma contro Cartagine and Mirko Basaldella’s Le repubbliche marinare.
