The Roman Forum

Remains of an ancient Roman City;

"The Roman Forum (also known as the Foro Romano, in Italian, or just the Forum) is one of the Top Ancient Sites in Rome as well as one of the Top Rome Attractions for visitors. Occupying a sprawling space between the Colosseum, the Capitoline Hill, and the storied Palatine Hill, the Forum was the center of political, religious, and commercial life of ancient Rome and provides insight into the splendor that once was the Roman Empire. The Via dei Fori Imperiali, built during the reign of Mussolini in the early 20th century, forms the eastern edge of the Forum." - About.com
