Natural accents for your garden, traditional cairns are stacks of rocks intentionally placed to mark a path or to serve as a monument of remembrance. Indeed their very name, a middle Gaelic word, means 'mound of stone built as a memorial or landmark.' Cairns cross deserts on three continents, dot the Tibetan plateau, and punctuate both the Mongolian steppe and the Inca road system of the Andes. Practical and decorative, they also hold deep spiritual value to many cultures. No two are alike, and dimensions may vary slightly.
