The EUR is a modern neighborhood - famous for its rationalist architecture, designed and constructed only for the Universal Exposition that would have been held in the capital in 1942, to celebrate the 20th anniversary of the March on Rome.

The event was later canceled because of World War II, and the neighborhood, still under construction, was completed at a later date.

There is also a museum-area that includes the Museum of Roman Civilization, the National Museum of the Middle Ages and the National Museum of Prehistory and Ethnography "Luigi Pigorini", in addition a new planetarium, with its Museum of Astronomy, was opened in 2004.
