The monument consists of about 38 vintage American automobiles, all covered with gray spray paint, arranged in a circle measuring about 30 meters in diameter. Some are held upright in pits 1.5 meter deep, trunk end down, and arches have been formed by welding automobiles atop the supporting models.
Carhenge replicates Stonehenge’s current dilapidated state, rather than the original stone circle erected between 2500 BC and 2000 BC. In addition to the Stonehenge replica, the Carhenge site includes several other artworks created from autos covered with various colors of spray paint.
Carhenge was conceived in 1987 by Jim Reinders as a memorial to his father and was dedicated at the June 1987 summer solstice. In 2006, a visitor center was constructed to serve the site.
