Lester Collins's Sculpture Garden at the Hirshhorn Museum in Washington, DC Photo: Ted Booth, 2010 A recent opinion piece about the controversial Hiroshi Sugimoto-led revitalisation of the Hirshhorn Museum’s Sculpture Garden omitted essential details about its historic significance and the critical need for maintenance and management. Most importantly, the Sculpture Garden, located on the National Mall in Washington, DC, and designed by architect Gordon Bunshaft (in 1974) and landscape architect Lester Collins (in 1981), is eligible for listing in the National Register of Historic Places and is part of the National Mall Historic District. Federal law aims to safeguard such historic design, making every attempt to avoid and/or limit “adverse effects”. Consequently, the op-ed’s attempt to provide a “larger context [for] the changing role of museums” by citing a number of global projects, including the Crystal Bridges Museum of American Art, which is a newly constructed institution and not an insertion in a National Register-eligible campus, is irrelevant.
