Isamu Noguchi’s “Sunken Garden,” completed in 1964, is the centerpiece of One Chase Manhattan Plaza. The boulders in the water garden were collected from the Uji River in Kyoto, Japan. Since 1972, it has shared the 2.5-acre plaza with Jean Dubuffet’s graphic, black-and white sculpture, “Group of Four Trees.” April 11, 1964.
