who built colosseum?

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 and son Titus. It was built to host public games and spectacles, such as gladiator fights, naval battles, and other forms of entertainment.

The Colosseum was designed by Roman architects and engineers, who used advanced techniques for the time, such as the arch and the vault, allowing them to build an imposing and durable structure. Its capacity was about 50,000 spectators, who could watch events from well organised seats.

After its inauguration, the Colosseum became a symbol of the power and greatness of the Roman Empire. Over the centuries, it has suffered damage from earthquakes and looting, but remains an important archaeological and tourist site, representing a cultural heritage of inestimable value.
