The Colosseum, also known as the Flavian Amphitheatre, is one of the most iconic monuments in Rome and in the history of architecture. Its construction began under Emperor Vespasian in 70 AD and was completed in 80 AD under his successor, Titus. The design of the Colosseum is attributed to a team of Roman architects and engineers, but no single designer can be identified.
The amphitheatre was built of travertine, a type of limestone, and is elliptical in shape, with a length of approximately 189 metres and a width of 156 metres. The structure could accommodate between 50,000 and 80,000 spectators, who watched gladiator fights, hunting shows and other forms of entertainment.
The Colosseum is an extraordinary example of Roman engineering, with a system of arches and vaults that guarantees stability and strength. Its design influenced the architecture of amphitheatres and stadiums around the world, making it an enduring symbol of the greatness of the Roman Empire.
