Colosseo
The Colosseum, originally known as the Amphitheatrum Flavium or simply the Amphitheatrum, is the largest amphitheater in the world. It is located in the city center of Rome. In 1990, the Colosseum, along with all the historical center of Rome, the Vatican extraterritorial zones in Italy and the Basilica of San Paolo Fuori le Mura, was listed as a World Heritage Site by UNESCO, while in July 2007 it was included among the New Seven Wonders of the World. Interventions were performed as regards remediation, restoration, and waterproofing of the third order and relative paths, in conjunction with the new opening to the public.
