The Championships, Wimbledon, commonly known simply as Wimbledon or The Championships, is the oldest tennis tournament in the world and is widely regarded as the most prestigious. It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, and since 2009 with a retractable roof over Centre Court, and since 2019, over No. 1 Court.
Wimbledon is one of the four Grand Slam tennis tournaments, the others being the Australian Open, the French Open and the US Open. Since the Australian Open shifted to hardcourt in 1988, Wimbledon is the only major still played on grass, which is widely considered as the classic tennis court.
