The Callanish standing stones (on the Isle of Lewis, Outer Hebrides) are about 5000 years old. Theories as to the meaning and purpose of the stones abound - many believe they were used in rituals relating to the moon, stars and the position of the distant hills. There are at least a dozen sites of interest around Callanish but this is the most impressive. The main stone complex contains about 50 stones in a cross-shaped setting and the inner circle (here) comprises 13 stones, the tallest of which is 4 metres high and a small chambered cairn.
Thank you for looking in and for your time - comments and criticisms are always welcome. I've convered to b&w with Lightroom preset B&W Creative Look 1 (with a few tweaks) as I think the image lends itself to this treatment more than colour.
