wall constructed without mortar, using enormous blocks of stone. This technique was employed in fortifications where use of large stones reduced the number of joints and thus reduced the walls' potential weakness.

Similar walls, though not called cyclopean, are found at Machu Picchu, Peru, and at several other pre-Columbian sites in the New World
