This is the course that Jack built, and rebuilt, and rebuilt again and again. Since its opening in 1974, Jack Nicklaus has remodeled every hole at Muirfield Village, some more than once, using play at the PGA Tour’s annual Memorial Tournament for some guidance. In the past eight years, he totally changed the par-3 16th and par-4 17th holes and added a new back tee to the par-4 18th, extending it from 444 yards to 484. That’s how a championship course remains competitive. But with every change, Nicklaus always made sure the general membership could still play and enjoy the course as well.
