The Fascist regime that ruled in Italy between 1922 and 1943 had its showcase in Rome. Mussolini ordered the construction of new roads and piazzas, resulting in the destruction of older roads, houses, churches and palaces erected during papal rule. The main activities during his government were: the "isolation" of the Capitoline Hill; Via dei Monti, later renamed Via del'Impero, and finally Via dei Fori Imperiali; Via del Mare, later renamed Via del Teatro di Marcello; the "isolation" of the Mausoleum of Augustus, with the erection of Piazza Augusto Imperatore; and Via della Conciliazione.
