A district born for a World's Fair that never happened

EUR is one of the few districts on earth designed entirely on the drawing board, following a single architectural vision. It took shape in the late 1930s to host the World's Fair of Rome in 1942 (hence the acronym EUR), conceived as a grand showcase for the regime. The war killed the event, and the district sat unfinished for years; it was later completed in the postwar period and reborn as a modern business and residential hub. The result is a singular area, suspended between 1930s monumentality and modernity.

The Rationalist (and "metaphysical") style

EUR's architecture is pure Italian Rationalism and the so-called monumental style of the era:

  • Pure geometric forms: cubes, arches, parallelepipeds.
  • Symmetry and repetition (the arcades of the Colosseo Quadrato, or "Square Colosseum").
  • Noble, Roman materials: travertine, marble, brick.
  • Vast open spaces, dead-straight avenues, and monumental sightlines.
  • Echoes of classical antiquity, reinterpreted in a modern key.

The atmosphere that emerges is solemn, almost "metaphysical," recalling the painted architecture of Giorgio de Chirico.

The landmark buildings

EUR's Rationalist style reads most clearly in:

  • The Palazzo della Civiltà Italiana (Palace of Italian Civilization), the Colosseo Quadrato (Square Colosseum), the district's manifesto.
  • The Palazzo dei Congressi, with its great arched facade.
  • The Basilica dei Santi Pietro e Paolo, monumental sacred architecture.
  • The office palaces lining the avenues, with their regular porticoes.

To these, in recent times, has been added Fuksas's Nuvola ("the Cloud"): proof that EUR remains a laboratory for architecture.

EUR on the big screen

EUR's one-of-a-kind atmosphere has drawn auteur cinema: directors like Michelangelo Antonioni (in L'eclisse, "The Eclipse") and Federico Fellini set memorable scenes here, using the empty, monumental spaces to capture alienation and modernity. For film buffs, spotting these locations is part of the thrill of a visit.

Why it's worth a visit

EUR is a must for anyone who:

  • Loves architecture and twentieth-century urban planning.
  • Is after a different Rome, monumental and photogenic.
  • Has a passion for cinema and metaphysical atmospheres.

In half a day it delivers a unique experience, far from the classic tourist circuits.

Frequently asked questions

Why does EUR have this architectural style? Because it was designed in the 1930s as a monumental district for the 1942 World's Fair, in the Rationalist style: geometric forms, symmetries, travertine, and echoes of antiquity reinterpreted in a modern key.

What does "Rationalist" mean? It's the twentieth-century architectural movement built on pure forms, function, and geometry. At EUR it fuses with a powerful monumentality, creating a solemn, "metaphysical" atmosphere.

Did the 1942 World's Fair actually take place? No: it was canceled because of World War II. The district, left unfinished, was completed in the postwar period.

Has EUR appeared in famous films? Yes: directors like Antonioni (L'eclisse) and Fellini shot celebrated scenes here, using the monumental, empty spaces to portray modernity and alienation.

Why is it worth visiting? For its unique twentieth-century architecture, its photogenic vistas, and an atmosphere unlike anything else in Rome: an ideal stop for fans of design, urban planning, and cinema.
