The Maryhill Stonehenge was the first monument in the United States to honor the dead of World War I (specifically, soldiers from Klickitat County, Washington who had died in the still on-going war). The altar stone is placed to be aligned with sunrise on the Summer Solstice. Hill, a Quaker, informed that the original Stonehenge had been used as a sacrificial site, therefore constructed the replica as a reminder that humanity is still being sacrificed to the god of war. The monument was originally located in the center of Maryhill, which later burned down leaving only the Stonehenge replica. A second formal dedication of the monument took place upon its completion on May 30, 1929. Sam Hill, who died in 1931, lived long enough to see his Stonehenge completed.
The dedication plaque on this Washington Stonehenge is inscribed:
"In memory of the soldiers of Klickitat County who gave their lives in defense of their country. This monument is erected in the hope that others inspired by the example of their valor and their heroism may share in that love of liberty and burn with that fire of patriotism which death can alone quench."
