In 1976, artist Nancy Holt installed Sun Tunnels in Utahâs Great Basin Desertâfour 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 solsticesâJune 21st and December 21stâwhen visitors can witness the sun framed in concrete, just as Holt intended.
