Classiebawn castle close to the head of Mullaghmore on County Sligo's Wild Atlantic Way, was the holiday home of Louis Mountbatten, a member of the British royal family who was assassinated close by in 1979. The pair of standing stones erected on the ground below the castle would seem to support the reputed occult interests of Lords Palmerston, Ashley and Mountbatten.

You can actually not access the castle area as is it private land, however, you have great views from the shore. There are view great angles, my favorite once are from up the little hill on the right, with the road in the foreground and also from the bottom if you walk down to the rocks (this is only accessible during low tide)
