Maryhill Museum of Art - Goldendale, WA - Near the town site of Maryhill, Washington, three miles east of Maryhill Museum of Art, stands a full-scale replica of Stonehenge built by museum founder Sam Hill.
Maryhill Museum, in southwest Washington, on the Columbia Gorge has a fantastic collection of art and artifacts, including practice sculptures by Rodin, and a life-sized concrete replica of Stonehenge, built as a memorial to WWI soldiers by Maryhill's creator, Sam Hill. When you hear "what in the Sam Hill?!" this is what they were talking about. http://www.maryhillmuseum.org/
