Detailed explanation-1: -Made primarily of concrete, 3.5 million cubic feet of travertine, and similar amounts of marble, stone and timber, the Colosseum rose to 157 feet (roughly the height of a 15-story building), with a capacity for an estimated 50, 000 to 80, 000 people.
Detailed explanation-2: -The three primary materials used in the construction of the amphitheater were tuff, concrete, and travertine. Travertine is a type of limestone that was regarded as a very strong construction material by the Roman builders. Tuff is a type of volcanic stone, which was used as a construction material due to its weight.
Detailed explanation-3: -The Colosseum uses several materials. The main one is travertine, a limestone, marble, for decorations, tuff, volcanic rock, brick, and lime for links. We also used metal, mainly bronze, to bind the stones together.
