Victor Emmanuel Monument

Also known as the "Wedding Cake" because of its shape, the Victor Emmanuel Monument is grandiose in the center of Rome. The building itself is quite a sight to see from the outside. However, the highlight is taking the glass elevator for 7 Euros (per person) in the back  of the building to the top. This offers excellent views over all of Rome, including the Forum Ruins and Colosseum in the back. Definitely plan to make a visit here during your trip to Rome.
