Wimbledon, is the oldest tennis tournament in the world, and widely considered to be the biggest and 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 its original name of “lawn tennis”. Since 2001 the courts used for Wimbledon have been sown with 100% perennial ryegrass. Prior to 2001 a combination of 70% ryegrass and 30% Creeping Red Fescue was used. The change was made to improve durability and strengthen the sward to better withstand the increasing wear of the modern game.
Note : The Grand Slam tournaments, also called majors, are the four most important annual tennis events. The Grand Slam itinerary consists of the Australian Open in mid January, the French Open in May and June, Wimbledon in June and July, and theUS Open in August and September. Each tournament is played over a period of two weeks. The Australian and United States tournaments are played on hard courts, the French on clay, and Wimbledon on grass. Wimbledon is the oldest, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905.
