The Championships have been held since 1877, and tennis's oldest tournament is steeped in history and tradition. The two-week event, hosted by the All England Lawn Tennis and Croquet Club in Wimbledon, southwest London, begins in late June. It's watched by millions around the world, and by up to 38,500 spectators each day. You can become one of the latter by joining a Queue so important it gets its own capital letter, either on the day of play or each evening. Foul weather can scupper the best-laid plans, unless they involve Centre Court – its retractable roof has guaranteed play since 2009.
