If you're interested in ancient sculpture, you should not miss one of Rome's greatest collections of classical antiquities, housed in this 16th-century building. It displays the collections of ancient Roman and Egyptian sculpture of the Museo Nazionale Romano. Look for two works in the famed Ludovisi collection: the large, intricately carved Ludovisi Sarcophagus and Galata, a poignant work portraying a barbarian warrior who chooses death for himself and his wife rather than humiliation by the enemy. The palace's stunning courtyard and gorgeously frescoed ceilings and loggia make an impressive setting for the sculptures. COST: EUR5.
