In 1976, artist Nancy Holt installed Sun Tunnels in Utah’s Great Basin Desert—four concrete cylinders aligned with the solstices and pierced with constellations. A pioneer of the Land Art movement, Holt transformed the desert into a celestial observatory, blending earth, light, and time into one quiet, monumental work.
The tunnels align perfectly with the rising and setting sun during the summer and winter solstices—June 21st and December 21st—when visitors can witness the sun framed in concrete, just as Holt intended.
