Natural Bridge, VA 24578
Made entirely of foam, Foamhenge is a full-size replica of the original Stonehenge in England. Mark Cline of Enchanted Castle Studios is its creator, and has made these structures out of Styrofoam. He admits going to great lengths to place these structures exactly at their right positions, to ensure that they are astronomically correct. The megalith structures are fixed into a hole at the ground, and attached with cement. Sitting on Natural Bridge, these 16 foot (5 meters) structures stand as proud copies of the original.
