Rock cairns are human-made stacks, mounds, or piles of rocks. They take different forms, and have been built by cultures around the world for many different purposes. Cairns may serve as monuments, burial sites, navigational aids (by land or sea), or ceremonial grounds, among other uses. This side by side stone cairn is a unique variation. With a very heavy base, it stands 17" tall and can be displayed indoors or outdoors.
