The partly completed monument was inaugurated on 4 June 1911, on the occasion of the Turin International world's fair and the 50th anniversary of Italian unification. Construction continued throughout the first half of the 20th century; in 1921 the body of the Italian Unknown Soldier was placed in the crypt under the statue of the goddess Roma, and in 1935 the monument was fully completed amidst the inauguration of the Museo Centrale del Risorgimento Italiano.
