The Maryhill Stonehenge is a replica of England’s Stonehenge located in Maryhill, Washington. It was commissioned in the early 20th century by the wealthy entrepreneur Sam Hill, and dedicated on 4 July 1918 as a memorial to the people who had died in World War I.
The memorial is constructed of concrete, and construction was commenced in 1918 and completed in 1929.
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 then on-going war. The altar stone is placed to be aligned with sunrise on the summer solstice.
Following the then-prevalent interpretation of Stonehenge, Hill thought that the original monument had been used as a sacrificial site. He was a Quaker, and commissioned the replica as a reminder that humanity is still being sacrificed to the god of war. 
The monument is located within the former site of the town of Maryhill; the town later burned down, leaving only the concrete replica standing. The memorial overlooks the Columbia Gorge. A second formal dedication of the monument took place upon its completion on 30 May 1929. Sam Hill died in 1931, but lived long enough to see the re-installation of his Stonehenge replica completed.
The dedication plaque on this Washington Stonehenge is inscribed:
In memory of the soldiers and sailors 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.
This concrete landmark is located off U.S. Highway 97, about two miles from where it enters Washington from Oregon, by crossing the Columbia River. Admission is free to visit the memorial; but donations for its continued maintenance are appreciated.
