EUR is a residential and business district in Rome, Italy located south of the city centre. The area was originally chosen in 1930s as the site for the 1942 world's fair which Benito Mussolini planned to open to celebrate twenty years of Fascism, the letters EUR standing for Esposizione Universale Roma. The project was originally called E42 after the year in which the exhibition was planned to be held. EUR was also designed to direct the expansion of the city towards the south-west and the sea, and to be a new city centre for Rome.
