The Colosseum is probably the most impressive building of the Roman empire. Originally known as the Flavian Amphitheater, it was the largest building of the era. The monumental structure has fallen into ruins, but even today it is an imposing and beautiful sight.
The elliptical building is immense. The Colosseum could accommodate some 55,000 spectators who could enter the building through no less than 80 entrances. Above the ground are four storeys, the upper storey contained seating for lower classes and women. The lowest storey was preserved for prominent citizens. Below the ground were rooms with mechanical devices and cages containing wild animals. The cages could be hoisted, enabling the animals to appear in the middle of the arena
The Colosseum was covered with an enormous awning known as the velarium. This protected the spectators from the sun. It was attached to large poles on top of the Colosseum and anchored to the ground by large ropes. A team of some 1,000 men was used to install the awning.
The southern side of the Colosseum was felled by an earthquake in 847. Parts of the building - including the marble facade - were used for the construction of later monuments, including the St. Peter's Basilica.
Nowdays, it's a bit of a Disneyland of kiss me quick Gladiators and long queues
