Pantheon, Rome

Nearly 2,000 years old, Pantheon is the only building from the Greco-Roman world that has remained substantially intact and in continuous use throughout its long history. A marvel of ancient architecture, it still boasts the world's largest unreinforced concrete dome. Originally designed to be a temple to all the gods of the ancient Rome, the site has been used as a Roman Catholic church, dedicated to St. Mary, since the seventh century. The building features large, granite Corinthian columns. Don't skip this site if it's raining; seeing and hearing the rain pouring into this ancient building through the hole in the ceiling is a special experience.
