Founded in 1978, Opus 40 is an earthwork sculpture park and museum located in Saugerties, New York. We bring natural and creative resources to the public through a park, museum, performance space and educational facility. Each year we offer a range of events and programs on our remarkable site.

Visitors can walk through, around, and over our 6½-acre sculpture, from the deepest recesses of its subterranean pathways (16 feet below ground) and up to the nine-ton monolith that is the epicenter and summit of the sculpture (three stories above ground).
