British Open

British Open, officially the Open Championship or the Open, one of the world’s four major golf tournaments—with the Masters Tournament, the U.S. Open, and the Professional Golfers’ Association (PGA) Championship—and the oldest continually run championship in the sport. Best known outside the United States as the Open Championship or, simply, the Open, it has been held annually (with a few exceptions) on various courses in Scotland, England, and—on one occasion—Northern Ireland since 1860.
