This full-size replica of Stonehenge overlooks Maryhill, Washington. It was built as a WWI memorial by Sam Hill. The memorial was dedicated in 1918 but not finished until 1930. Hill died shortly after the replica’s completion and is buried at the base of the bluff. Hill apparently got the idea for such a memorial when he was mistakenly informed that the original Stonehenge was used for sacrifice. Thus, he constructed this replica to show the sacrifices of WWI.
My research shows that the trip would take about an hour and 45 minutes so we would probably have to do this outside of class, or start earlier/go later. There is no admission fee.
