<P> A links is the oldest style of golf course, first developed in Scotland . The word "links" comes via the Scots language from the Old English word hlinc: "rising ground, ridge" and refers to an area of coastal sand dunes and sometimes to open parkland . Links land is typically characterised by dunes, an undulating surface, and a sandy soil unsuitable for arable farming but which readily supports various indigenous browntop bents and red fescue grasses, that result in the firm turf associated with links courses and the' running' game . It also retains this more general meaning in standard Scottish English . It can be treated as singular even though it has an "s" at the end and occurs in place names that precede the development of golf, for example Lundin Links, Fife . </P> <P> Links courses tend to be on, or at least very near to, a coast, and the term is typically associated with coastal courses, often amid dunes, with few water hazards and few, if any, trees . This reflects both the nature of the scenery where the sport happened to originate and the fact that only limited resources were available to golf course architects at the time and any moving of soil had to be done by hand, so it was kept to a minimum . Even today, some links courses do not employ a greens staff, use only basic machinery such as hole cutters without boards resulting in a hole that is cut unevenly, and use grazing animals to keep the grass cropped . </P> <P> Although the term links is often considered synonymous with any golf course, few golf courses have all of the design elements of true links courses, including being built on linksland . The presence of a seaside location does not guarantee a links golf course . Many famous courses that claim to be links do not have all of the necessary characteristics (e.g., Pebble Beach Golf Links, Old Head Golf Links at Kinsale, The Ocean Course at Kiawah Island). On the other hand, some courses located hundreds of miles from a coast can have all of the characteristics of a seaside links except for proximity to water . </P> <P> Links courses remain most common in Ireland and Great Britain, especially in Scotland . The Open Championship is always played on links courses, and this is one of the main features which differentiates it from the three major championships held in the United States . The first exception to this was the 2004 PGA Championship, which was played on a true links course, Whistling Straits, located near Kohler, Wisconsin . The 2015 U.S. Open was played at Chambers Bay, a British links - style course in University Place, Washington . Royal Adelaide Golf Club is a world - famous links course in Adelaide, South Australia and was partly designed by Alister MacKenzie where he stated, "One finds a most delightful combination of sand dunes and fir trees . I have never seen a seaside course possess such magnificent sand craters, as those at Royal Adelaide ." </P>
