Cairns (German: Steinmännchen) exist all over the world in all sorts of shapes from small piles to artificial hills or delicately balanced sculptures and sizes to mark trails and special areas. Sometimes they are painted or decorated for increased visibility or religious reasons.
I love these little architectural masterpieces which seem so beautifully balanced.
They have existed for centuries and whenever I see one it looks as if they have been exactly in this place forever. This cairn I saw at the beachside of Monterey, California.
