The Colosseum, the Marcello Theater, the Trevi Fountain, the Colonnade of St. Peter, the Basilica of Santa Maria Maggiore, the Bernini Fountains, the Triumphal Arches, the Baroque Churches and the Imperial Palaces are just some of the countless monuments that the ancestors of our territory created with Roman travertine - a material appreciated and used even in recent times, both in modern and classical architecture. In the capital, travertine has its well-deserved role as a precious ornamental construction material for the Palace of Justice, the University City, the Palazzo della Civiltà e del Lavoro, the Olympic Stadium and the Mosque in Rome.
