Like many other parts of the world, Britain has its fair share of ancient stone circles. See for example, the stones on the Orkney Islands.
Near the Loch of Stennis there were two large stone circles, dedicated the sun and moon. Until just two hundred years ago, a bride would walk around the circle of the moon stones, and the groom would circuit the sun stones. They then met at the huge Odin Stone which had a circular hole. They would join hands through this hole, plight their troth, and become man and wife.
It is believed the stone was erected there 5,000 years ago. But two hundred years ago it was destroyed by grumpy landowner Captain Mackay, who was tired of the hoards of visitors to the stones. Marketing, as we know it today, was in its infancy then.
