Although Muirfield is a links course as it is set upon elevated ancient land claimed from the sea as highlighted by its sandy base and small sea shells in the bunkers, it has an unusual layout. Most links courses run along the coast and then back again leading to two sets of nine holes, each of which face roughly in the same direction. Muirfield, however, was amongst the first courses to depart from this arrangement and is arranged as two loops of nine holes, one clockwise, one counterclockwise. This means that, assuming the wind direction remains the same throughout a round, every hole on the course has a different apparent wind direction from the tee.No more than three consecutive holes follow the same direction at any stage.
