The Palazzo degli Uffici dell'Ente Autonomo at the E.U.R. area in Rome. In 1939 this was the first building to be finished as part of the Esposizione Universale Roma. It housed the offices for the exhibition and a large hall and was designed by Gaetano Minucci. Photo by Space 4.

The Square Colosseum also known as Palazzo della Civiltà Italiana, was built the symbolize Rome's district Esposizione Universale Roma (EUR). The EUR is now a large business center and suburban district in Rome.
