The Colosseum is one of Rome's most famous buildings. Initiated by Vespaisian, the official opening ceremonies were conducted by Emperor Titus in AD 80. In its prime the huge theater consisted of four floors. The first three had arched entrances, while the fourth floor utilized rectangular doorways. The floors each measured between 10,5-13,9 meters (32-42 feet) in height. The total height of the construction was approximately 48 meters (144 feet). The arena measured 79 x 45 meters (237-135 feet), and consisted of wood and sand. (The word "arena" is derived from the Latin arena, which means "sand.") Nets along the sides protected the audience. The Colosseum had a total spectator capacity of 45,000-55,000. The main pedestals were built of marble blocks weighing 5 metric tons (11,000 pounds.) Initially the huge marble blocks were held together by metal-pins. However, the pins were soon carried off by thieves, and had to be replaced by mortar. The total amount of marble needed for the construction measured approximately 100,000 cubic meters. It was carried by 200 ox-pulled carts, which supplied a sufficient flow of needed materials. It took eight years to complete this magnificent structure. .
