Travertine is derived from the Italian travertino, itself derived from the Latin tiburtinus, meaning 'of Tibur,' now known as Tivoli near Rome, where the travertine has been mined for at least two thousand years. In modern architecture, travertine is one of the most commonly used stones. Generally, it is used for indoor flooring, outdoor patio flooring, spa walls and ceilings, façades, and now furniture.
