The Wimbledon Championships, commonly called Wimbledon, is a tennis tournament organised by the All England Lawn Tennis and Croquet Club in collaboration with the Lawn Tennis Association annually in Wimbledon, London. It is chronologically the third of the four Grand Slam tennis events each year, held after the Australian Open and the French Open and before the US Open. It is the oldest tennis tournament in the world and is widely regarded as the most prestigious.
Wimbledon has been held since 1877 and is played on outdoor grass courts; it is the only tennis major still played on grass, the traditional surface. It is also the only major that retains a night-time curfew for logistical reasons, with matches continuing until 23:00 BST under floodlighting since 2009.
