Longtime New York theater impresario Billy Rose approached Noguchi in 1961 about what would become his largest commission to date in terms of acreage, a sculpture garden for the archaeology and art museum planned to open in Jerusalem in 1965. Noguchi created what was essentially his first earthwork in shaping the hillside of the Neve Shaanan (“place of tranquility”) with five massive retaining walls made of boulders from the site that face west to create “a play between the sky and the horizon.” To this newly tamed slope he added triangular stone wall sections as backdrops for the museum’s sculpture collection, and a massive stone fountain.
