It was first held in 1877 and has been held at the All England Club in Wimbledon ever since. Part of the four Grand Slam tennis tournaments, Wimbledon is now the only grand slam completion to be played on grass, which is how the name lawn tennis was formed. The main Centre Court and No. 1 Court, are normally used only for two weeks a year, during the Wimbledon Championships.
