Colosseum is certainly the most famous monument in the ancient world, and has been watching over the city of Rome for almost two thousand years. Its bricks and its travertine slabs are the symbol of the city but also of the entire Roman civilization. It is the largest amphitheater in the ancient world with a capacity of over 50,000 spectators.
Necropolis of Tarquinia, called also Etruscan necropolis of Monterozzi, overlies on a highland to the east of the city with some 6000 tombs, many of which were covered by tumulus with chambers carved in the rock below. The oldest ones date from VII century BC. Among thousands graves, at least 200 are decorated with a number of frescos which are the main core of the Etruscan art came to us.
