Built in honour of Victor Emmanuel, the first king of a unified Italy, this vast structure may appear to be solid white marble but actually contains many rooms inside. There are two permanent museums, one on Italian Reunification and one on emigration from Italy, as well as other spaces that host rotating exhibitions. A walk through the Flag Room leads to the tomb of the unknown soldier. Good views from half-way up but you can also pay €10 (€2 concessions) and take a lift all the way to the top.
The Victor Emmanuel II National Monument, also known as the Vittoriano or for synecdoche Altare della Patria, is a large national monument built between 1885 and 1935 to honour Victor Emmanuel II, the first king of a unified Italy, in Rome, Italy. It occupies a site between the Piazza Venezia and the Capitoline Hill. The monument was realized by Giuseppe Sacconi.

Ballroom-like church which crowns part of the Capitoline Hill. Don't be fooled by the plain stone exterior.
More of an enormous traffic circle than a piazza, but a good central location. The centerpiece is the enormous Vittorio Emanuele Monument (aka the Wedding Cake or the Typewriter) with the Capitoline hill next door. Mussolini used to harangue Romans from the first floor balcony of Palazzo Venezia (see under Museums), to the west of the square.
Capitoline Museum
Built in the 17th century to a design based on an architectural sketch by Michelangelo. Highlights include the ancient Colossus of Constantine statue (the Colosseum was probably named for another giant statue, the Colossus of Nero which stood near the Flavian Amphitheatre as the Colosseum was originally known), The Dying Gaul, a magnificent marble sculpture that copies a bronze Greek original of the 3rd century BC and the Capitoline Venus. It also contains the remarkable original gilt bronze equestrian statue of emperor Marcus Aurelius (the one in the piazza is a replica).
Museo Nazionale del Palazzo di Venezia
In the very heart of the city center, the building was for centuries ago the seat of the Venice embassy. Today it houses a museum and art galleries.
On top of the Capitoline hill. The piazza was designed by Michelangelo. The Capitoline Museum is housed in the palaces flanking the piazza. You can walk behind the Palazzo Senatorio, where Rome's government meets, to a wonderful viewpoint which overlooks the entire Roman Forum. In the centre of the square you can admire an exact copy of the Statue of Marcus Aurelius on horseback; the original is kept in one of the two museums, to preserve it from pollution.
Capitoline Museums
The two museums are on opposite sides of the Piazza del Campidoglio, It is recommended to book tickets online
