The All England Lawn Tennis and Croquet Club, also known as the All-England Club, based at Church Road, Wimbledon, London, England, is a private members' club. It is best known as the venue for the Wimbledon Championships, the only Grand Slam tennis event still held on grass. Initially an amateur event that occupied club members and their friends for a few days each summer, the championships have become far more prominent than the club itself. However, it still operates as a members' tennis club, with many courts in use all year round.
