The Country Club, located in Brookline, Massachusetts, is one of the oldest country clubs in the United States. It holds an important place in golf history, as it is one of the five charter clubs that founded the United States Golf Association, and has hosted numerous USGA tournaments including the 1913 U.S. Open won by then-unknown Francis Ouimet. Today, the club has nearly 1300 members.
The golf facilities have a total of 27 holes, divided between two courses.
The Main Course is composed of the Clyde and Squirrel nines, essentially the original 18 holes. This was the course used for the 1913 U.S. Open, and is the course played by members today.
The other nine holes are the Primrose Course, an executive course built in 1927. This was designed by William S. Flynn, who also (re)designed Shinnecock Hills, Cherry Hills Country Club near Denver, and the Cascades Course at The Homestead, and the Kittansett Club also in Massachusetts.
The Championship, Composite, Anniversary, or Open Course is used for major competitions today, when a longer layout is required. In this configuration, three and a half holes from the Primrose Course are used to replace three holes of the Clyde, resulting in a length of almost 7,400 yards. This layout has been used for major competitions since the Primrose Course was built.
