Do NLE courses count? There was once a course in St Augustine FL that was routed around the old Spanish fort. There were tee boxes located on the fort's parapets. There were greens located inside and outside the fort.
Not sure when the course disappeared, but I'd guess it is not highlighted in the the US Parks Service brochures.
BTW, even without the old golf course, the fort is worth a visit. Many years ago we took our kids to visit it and, just up the road, Gomeck, the giant alligator. I've heard that he is also NLE.
