In which country is the world's oldest surviving bowling green located?

Southampton Old Bowling Green, situated on the corner of Lower Canal Walk and Platform Road, Southampton, England, is the world's oldest surviving bowling green (finely laid, close-mown and rolled stretch of turf for playing the game of bowls). It was first used in 1299. Chesterfield Bowling Club in Derbyshire is believed to date back to 1294.

The Hospital of "God's House" was founded in 1185 for pilgrims who were going either to the shrine of St Swithun at Winchester or to Canterbury; until 2011, the gateway housed the museum of archaeology.

The green adjoining the God's House Hospital had been established during the reign of Richard I the Lionheart for the recreational use of the Warden, and was first used for a game of bowls in 1299.

The club that plays there now is believed to have been established in the 17th century because of the history of a competition known as the "Knighthood".

A unique occurrence called the "Knighthood" competition is held annually when the members (gentlemen commoners) compete to obtain 7 points, with the winner being awarded the title of "Knight-of-the-green" and becoming a sir. The competition is adjudicated by the members who have previous won the competition (Knights), who adjudicate in top hats and frocked tails suits. Those who win are unable to compete again in future Knighthood competitions.

This is the annual competition of the club with rules which are different from the normal variant of the game.
