colosseum how was it built?

The Colosseum, also known as the Flavian Amphitheatre, is one of Rome's most iconic monuments and its construction began in 70 AD under Emperor Vespasian, to be completed in 80 AD by his son Titus. The structure was built using mainly travertine, a type of limestone, and tuff, a volcanic material. The choice of these materials ensured both the solidity and durability of the building.

The construction of the Colosseum required a great deal of engineering effort. The elliptical plan of the amphitheatre measured about 189 metres long and 156 metres wide, with a height of about 48 metres. The structure consisted of four levels, three of which had arches, while the fourth was a service level. The arches and columns, in Doric, Ionic and Corinthian styles, gave it a majestic appearance.

Thousands of slaves and workers were employed for the construction, and an estimated 100,000 cubic metres of materials were used. The Colosseum was not only used for gladiator fights, but also for public spectacles and theatrical performances, becoming a symbol of the power and culture of the Roman Empire.
