Travertine is a natural stone built up over the years by the calcification of various minerals combined with water from geothermal hot springs, such as those found in Yellowstone National Park. It is an extremely porous material that is filled with pockets of air that have been trapped within the stone during the formation, and these natural imperfections in conjunction with the durability of travertine have culminated in a natural product.The Coliseum in Rome is made of travertine.
