Fodor's Expert Review Calanais Standing Stones
The west coast of Lewis is rich in prehistoric sites, and the most famous of these is the Calanais Standing Stones. Believed to have been positioned in several stages between 3000 BC and 1500 BC, this arrangement consists of an avenue of 19 monoliths extending northward from a circle of 13 stones, with other rows leading south, east, and west. Ruins of a cairn sit within the circle on the east side. Researchers believe they may have been used for astronomical observations, but you're free to cook up your own theories. The visitor center has an interesting exhibit on the stones, a very pleasant tearoom, and a gift shop.
