The Colosseum is with no doubt the most renown symbol of Rome all around the world. It was built in the I century by emperor Vespasian and his son Titus: inhaugurated with the name of Flavius Amphitheatre, it was almost immediately called Colosseum by the name of gigantic statue of Nero that was nearby.

It is the largest amphitheatre of the whole Classic Age, since it has a circumpherence of 527 meters and it is 57 meters high. Initially it was all covered by marbles, taken during the Renaissance for the construction of the new Cathedral of St. Peter and of some palaces of Papal Court. In the XVIII century it was declaired by pope Benedict XIV as monument to the memory of Christian Martyrs, so it could save its current state.

For the enjoyment of Rome people, here were organized fights between gladiators or against wild animals and fabulous spectacles as "naumachie", real navy battlements in the arena filled with water. The most impressive spectacles were performed in occasion of the millenary of Rome foundation in 249, with thousands of gladiators and hundreds of wild and exotic animals.

The amphitheatre could host about 50.000 people and was an extraordinary architectural achievement, which gives evidence of the building knowledge and technology reached by Romans.
