The Colosseum was originally called the Flavian Amphitheater and could seat some 55,000 people. Most of the games in the Colosseum involved fights to the death either between gladiators

and exotic animals or between gladiators.

The Trevi Fountain is arguably one of the world's most beautiful fountains. Its construction began in 1732 and was completed in 1762. The fountain is located at the end of the Aqua Virgo, an

aqueduct built in 19BC which brings water from the Salone Springs.

The Pantheon was constructed as a temple for all pagan gods and and was later converted into a church in 609AD. It contains the tombs of several Italian kings and the artist Raphael. The interior

design contrasts somewhat with the architectural design, except that the marble floor still features the original marble design. The dome is considered an architectural achievement and was the largest dome in existence from the time it was built until 1436 when the Florence Cathedral was built.

Whether you're Catholic or not, the Vatican is not to be missed. The Vatican is the seat of Catholicism, and holds some of the most beautiful trappings of religion seen anywhere in the world. In

addition, the Sistine chapel, with the ceiling painted by Michaelangelo as well as other incredible artwork, is not to be missed. Also not to be missed are the four rooms forming the Stanze of Raphael, which feature the works of Raphael and others from his school. Be sure to see the Upper Galleries of Tapestries as well, as the Vatican has some of the most incredible tapestries ever made.

Henry James considered these gardens the “most enchanting place.” Covering 17 acres and offering a fantastic panoramic view of Rome, these gardens were build to surround the Villa de Medici.

The Villa looked like a fortress and the gardens helped mask its severe facade.
