(*As of the 2016 Open, Muirfield has been removed from the rota by the R&A because of a club vote to allow women members that came up short. The club is seeking to hold another vote.)
Where: Gullane, East Lothian, Scotland
Times hosting:16 (last in 2013)
You know it as: "That course where Tiger shot an 81 in monsoon conditions to end his hope of capturing the calendar Grand Slam in 2002."
Unique features: Home to the oldest organized golf club in the world, The Honourable Company of Edinburgh Golfers, whose records date back to 1744; Circular routing in which the front nine wraps around the back nine.
Noteworthy moments: Jack Nicklaus won his first of three Opens here in 1966 (left) and named his own course in Dublin, Ohio, Muirfield Village, after it. Muirfield was also the site of the 1892 Open, golf's first four-round tournament. In 2013, Phil Mickelson shot one of the great final rounds ever (66 in tough conditions) to capture his first claret jug.
