Colosseum, Rome

Considered one of the greatest works of Roman architecture and engineering, Colosseum is the largest amphitheater in the world. This world-famous Roman landmark is one of the city's most visited attractions, so expect a long line and an even longer wait. Skip the long line for the general entry by joining a guided tour of the site or by booking your tickets online. Built of concrete and stone, the elliptical amphitheater was originally capable of seating some 50,000 spectators who came to watch animal fights and gladiatorial combats. Emperor Vespasian began the amphitheater project in 70 CE. It was completed during the reign of Titus about ten years later, measuring 48 m (157 ft) high, 188 m (617 ft) long, and 156 m (511 ft) wide.
