The Eton Wall Game
This is as exclusive as sports get. The Eton Wall Game has just one important match a year, there's just one pitch in the world, and you have to be connected to Eton College - one of the world's most exclusive schools - to play.
But while the outfits and rules of the game seem like something from a bygone era, the sport is still going strong today.
