ARCHITECTS: The Country Club evolved as a collaborative design. In 1893, the first six holes were designed by the club’s first golf committee, which comprised members Arthur Hunnewell, Laurence Curtis and Robert Bacon. Willie Campbell was hired as the professional in 1894 and helped add three new holes and redesign the original six. The club expanded to 18 holes in 1899. William Flynn designed a third nine in 1927, which is called Primrose.

The course used for championships, including the 2013 U.S. Amateur, is a composite that incorporates three-and-a-half holes from the Primrose. Geoffrey Cornish made changes before the 1963 U.S. Open. Rees Jones supervised revisions to the course before the 1988 U.S. Open. Gil Hanse has also done some recent restorations to the course. Charles River Country Club was designed by Donald Ross and opened in 1921.
