The most important Fascist site in Rome is the EUR district, designed in 1938 by Piacentini. This new quarter emerged as a compromise between Rationalist and Novecento architects, the former being led by Giuseppe Pagano. The EUR was originally conceived for the 1942 world exhibition, and was called "E.42" ("Esposizione 42"). The most representative buildings of EUR are the Palazzo della Civiltà Italiana (1938–1943), and the Palazzo dei Congressi, examples of the Rationalist style. The world exhibition never took place, because Italy entered the Second World War in 1940, and the buildings were partly destroyed in 1943 in fighting between the Italian and German armies and later abandoned. The quarter was restored in the 1950s when the Roman authorities found that they already had the seed of an off-centre business district of the type that other capitals were still planning (London Docklands and La Défense in Paris). Also, the Palazzo della Farnesina, the current seat of the Italian Ministry of Foreign Affairs, was designed in 1935 in pure Fascist style.
