Stonehenge Replica, Washington

Sam Hill built this Stonehenge-shaped monument out of reinforced concrete, with wrinkled metal forms to give the concrete a rock-like texture. It was constructed between 1918 and 1929, as a World War One memorial, and is located on a dramatic, hillside location, overlooking the Columbia River (and only a few miles away from his chateau, now the Maryhill Museum). Though similar to the original Stonehenge in form, the structure has little astronomical or astrological utility. Hill is buried in a 14-ton granite crypt downslope from the monument, and the area is ringed by experimental roads, built by Hill and his engineers. Now abandoned, these were the first rural paved roads in the state.
