Sunningdales Old Course was designed by Willie Park Junior and opened in 1901. It was laid out in the last days of the gutty ball, over a mixture of hills, heath and woodland that had hitherto not been considered as suitable for golf course construction. Urns containing fourteen iron-age Skeletons were excavated during its construction. The course was considered extremely long and its popularity owed much to the development of the Haskell ball, initially imported from the United States.

Willie Parks design was considered revolutionary at the time, and within a few years Harry Colt, the Club Secretary, had modified several holes and drastically altered others. Bernard Darwin in Golf Courses of the British Isles, 1910 believed that several of the holes had been greatly improved by the Colt changes.

The Old Course is considered one of the best inland courses in the UK and is regularly found in various 100 top courses rating lists. Many amateur and professional golfing events have been played here including the News of the World Professional Match Play Championship, numerous European Open Championships, many Ladies Open Championships, the Walker Cup, International Final Qualification for the Open Championship, and most recently the Senior Open Championship in 2015.
