All the Romans liked to go to the theater to watch concert and plays. They also liked to go to the stadium to watch chariot races and to the amphitheater to watch sports. Among all these, perhaps going to the amphitheater i.e. Coliseum was the most popularly accepted by the Romans. Gladiatorial combats, fights with beasts and other fights were held in the Coliseum. It was big enough to accommodate almost 50,000 people. Sometimes the whole population of the town used to spend their whole day by watching sports over there. The games that were performed over there were really bloody and for four centuries many men gave their lives to entertain the people. There were many frightful/dangerous games like, bear against buffalo, buffalo against elephant, and elephant against rhinoceros. Sometimes there would even be fights between men and these wild beasts. These fights were known to as venations.

The Amphitheater was built by travertine from the outside, and brick and tufa in the interior side. Many Greek columns were used for decorating the outside. Coliseum stands four stories high. The circumference and height of Coliseum was 527m and 50m respectively. There were all total 80 entrances and all were numbered except the for main entrances. These four were much more wider than the others and were reserved for only the Emperor. The interior was divided into three parts: the arena, the podium, and the cave. It was designed in such a way that the accumulated crowd could easily came out in not more than five minutes. At present more than tow-thirds of the original building has been disappeared and some rows of the seats in the cave are missing.

Coliseum still continues to inspire architects of the modern day, and virtually every modern sports stadium still bears the irresistible imprint of the Coliseum's original design. Until the 19th century, it remained the largest amphitheatre in the world.
