The Colosseum, also known as the Flavian Amphitheater, is the largest and oldest amphitheater in the world, located in Rome, Italy. It was famous for gladiator fights with each other and against wild animals. Later, in 404, these tortures were declared illegal.

Unlike the Greek theaters, which were built on one side against the hill, the Colosseum is a free-standing building. Its structure is similar to two Roman amphitheatres facing each other. These were hemispherical, with the stage on one side and the audience seats on the other. The stage is elliptical, 76×46 m. The size of the structure reaches 185×156 m, the height of the outer wall is 48 m. It is built of large stones connected by metal reinforcements.

The construction of the Colosseum began in 72 AD during the reign of Emperor Vespasian, the founder of the Flavian dynasty, and was completed in 80 AD during the reign of Emperor Titus. As long as the Colosseum stands, Rome stands, the Romans used to say, – When it collapses, Rome will also collapse, and with it the world.
