How many tournament grass courts does Wimbledon have?

The Championships, Wimbledon, commonly known simply as Wimbledon, is the oldest tennis tournament in the world, and is widely considered the most prestigious. It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts.

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.

There are a total of 19 tournament grass courts. The main show courts, Centre Court and No. 1 Court, are normally used for only two weeks a year, during the Championships, but play can extend into a third week in exceptional circumstances. The remaining 17 courts are regularly used for other events hosted by the Club. The show courts were in action for the second time in three months in 2012 as Wimbledon hosted the tennis events of the 2012 Olympic Games. One of the show courts is also used for home ties of the GB teams in the Davis Cup on occasions.
