It also cites the number of major national championships played there, including six U.S. Opens, and its role in the development of golf course design.","narrative":"Laid out in 1903 near the town of Oakmont, Pennsylvania, on former pastureland with gravel and clay soil, this 18-hole course was built by a group of Pittsburgh golfers and designed by Henry C. Fownes, an amateur golfer. Its narrow fairways, large sloping greens and profusion of sand bunkers made it the first comprehensive example of penal golf architecture, and it is regarded as a prototype for later courses of that type. William C. Fownes Jr. later refined the course, especially its bunkering, between 1911 and 1948. The course has hosted 13 major national championships, including six U.S. Opens, more than any other course in the country. Its layout remains largely original, and the Tudor Revival clubhouse of 1904 and nearby 1930s buildings form the associated club complex.","period_of_significance":"1903","architect_builder":"Henry C.
