Sun Tunnels 1976

"Sun Tunnels", created in 1976 by Nancy Holt, is a site-specific land art installation consisting of four concrete tunnels arranged in a cross shape. The tunnels are aligned with the solstices and equinoxes, creating a celestial viewing device that frames the sun at these significant points in the Earth's rotation. Holt's work engages with the natural world and its astronomical cycles, inviting viewers to consider their place within the universe.
