Italian police officers patrol a large area around the "La Nuvola" convention centre as preparations to welcome the leaders attending the G20 summit get underway. G20 leaders will meet in Rome's historic surroundings of EUR, a neighbourhood created by Benito Mussolini to glorify his fascist regime and its links with ancient Rome. Leaders will gather in a futuristic convention centre known as the "Nuvola" (cloud), featuring a suspended structure inside a glass and steel box, in a southern suburb with more easily policed boulevards and its own unique charm.
