The course is known for its particular physical features including 112 bunkers, some of which are especially famous e.g. 'Hell' on the long 14th, 'Strath' on the short 11th and the Road Bunker at what is probably the most famous golf hole in the world, the 17th or Road Hole (so called because a road - which is in play - runs hard against the back edge of the green). Another peculiar feature of the Old Course is the double greens where the outward and inward holes are cut on the same putting surface. These greens are large, not surprisingly, and golfers can be faced with putts of almost 100 yards.
The Old Course is also unusual in that it starts and finishes in the town, but its truly remarkable feature is that in today's modern golfing world, a course which has evolved over six centuries, remains a true test of championship golf.
