The Vatican is a precious stone from Tivoli in Rome, Italy. It belongs to the best of the travertine. The use of the stone by humans can be traced back to ancient times. One of the representative buildings of Roman culture, St. Peter’s Basilica, used a large amount of such travertine. Marco Polo’s Vatican has a variety of colors, rich textures and clear stripes, which cater to the urban people’s pursuit of natural and simple life aesthetics.
