Stone rings have amazed and perplexed people for centuries.
The Callanish stones in the Isle of Lewis are no exception. A local legend states that the stone rings of Callanish were found many hundreds of years ago by a farmer looking for large rocks to build a wall. Wandering across the desolate windswept moors of the Isle of Lewis, he stumbled upon a single large stone jutting from the ground. Hoping to remove it, he began to dig for its base, but as he dug deeper into the earth, other stones appeared. It was about this time that the weather in much of northern Europe cooled, the previously clear skies clouded over and consistent astronomical observations thereby became impossible.
