The Championships, Wimbledon, or simply Wimbledon is the oldest tennis tournament in the world, considered by many to be the most prestigious. It has been held at the All England Club in Wimbledon, London since 1877. It is one of the four Grand Slam tennis tournaments, the other three Majors being the Australian Open, French Open and US Open. Wimbledon is the only Major still played on grass, the game's original surface, which gave the game of lawn tennis its name.
