The Colosseum is the largest amphitheatre in the world, located in the centre of Rome, and the most important Roman amphitheatre as well as the most imposing monument of Ancient Rome that is still in existence today.
The amphitheatre was built during the Flavian Dynasty on an area at the eastern edge of the Roman Forum. Its construction was begun by Vespasian in 72 A.D. and it was inaugurated by Titus in 80 A.D.
In ancient times it was used for gladiator performances and other public manifestations. After the 6th century it fell into disuse and the enormous structure.
