The Duchess' Course, also designed by Charles Lawrie, opened in April 1978, two years after the Duke's Course.  The course design encompasses a ridge across the 5th and 11th fairways, which are the site of an ancient Danish settlement.

Although slightly shorter, the Duchess Course offers a different challenge.  Accurate driving and pinpoint iron play are the order of the day on a course with narrower fairways and approaches to greens.  Anyone who has played the course knows this is a layout that demands as much respect as the adjacent Duke's and Marquess courses.
