The Monumento Nazionale a Vittorio Emanuele II is located just within walking distance from the Colosseum. This magnificent yet controversial white marble monument that dominates Piazza Venezia was built to pay tribute to Victor Emmanuel II, the first king of a united Italy. Within the monument, the Museo Centrale del Risorgimento is housed. This is a museum dedicated to the history of how Italy was unified. The top of the monument provides a fantastic 360º panoramic view of Rome.
