A clay court is one of the types of tennis court on which the sport of tennis is played. Clay courts are built on a foundation of crushed stone, brick, shale, and other aggregate, with a thin layer of fine clay particles on top. Clay courts are more common in Continental Europe and Latin America than in North America, Asia-Pacific or Britain. The only Grand Slam tournament that uses clay courts is the French Open.
