Tate Liverpool: Sun Tunnels

Sun Tunnels 1978 is artist Nancy Holt’s best known work and this 26-minute film documents the making of her large-scale sculptural installation in the Utah desert. The film shows the construction of four huge concrete tunnels that are positioned to align with the sunrise and sunset of the summer and winter solstices. It features footage of these sculptures as they frame the sun and capture and cast the sunlight into different patterns. The work brings together themes of art, architecture and ecology.
