The Smithsonian defines its South Mall Campus as the area between 7th and 12th Streets that encompasses the nationally landmarked Freer Gallery of Art (1923), Smithsonian “Castle” (1855), and Arts & Industries Building (1881), as well as the Hirshhorn Museum and Sculpture Garden (1974).  The Campus also includes these structures in the Quadrangle behind the Castle:

  • The three entrance pavilions designed by noted architect Jean Paul Carlhian for the underground National Museum of African Art, the Arthur M. Sackler Gallery, and the S. Dillon Ripley Center;
  • The Victorian Enid A. Haupt Garden designed by landscape architect Lester Collins; and
  • The Renwick Gates, constructed from James Renwick’s original 1849 design, now the southern entrance to the garden.

Completed in 1987, the Quadrangle complex was the mastermind of Secretary S. Dillon Ripley as his final contribution to the Smithsonian’s legacy on the Mall.  An equally important contribution was the inspiration and generosity of Enid Haupt, who funded the garden named in her honor and an endowment for its upkeep.  The garden, with its Victorian seating and water features, has over the years become a cherished and contemplative refuge from the bustle of the Mall.

In 2013 the Smithsonian announced its intention to undertake an extensive and controversial “updating” of the features in the Campus and retained the Danish firm Bjarke Ingels Group (BIG) to produce a Master Plan that was estimated to cost over $2 billion.  While internationally recognized for innovative contemporary design, the firm had no experience working within an American historic context.  The plan proposed alterations in all of the buildings and landscape in the Campus.  Most egregious was the  proposal in the Quadrangle for the complete elimination of the Haupt Garden, the Renwick Gates, and one of the pavilions, and the demolition, relocation, and simplified redesign of the two other pavilions.

Led by the Committee of 100, opposition to the proposed losses—and especially the Haupt Garden—poured in nationwide from such organizations as the National Trust for Historic Preservation, the 18,000-member Garden Club of America, the Garden Conservancy, the Washington Post, the National Mall Coalition, the DC Preservation League, and leading scholars in American landscape and architectural history.  Over 2,300 individuals signed an on-line petition opposing the destruction of the Haupt Garden.   The Committee of 100 then prepared and submitted an application that successfully listed the Quadrangle structures on the DC Inventory of Historic Sites.

The success of these groups has been limited.  The Master Plan has been modified to preserve the Renwick Gates and to reinstate a radically redesigned garden. Two entrances to the underground museums have been provided by new glass-fronted structures.  In a minor victory, the plaza walls around the Hirshhorn will be retained, but a proposal is currently in progress for significant modifications of the Hirshhorn Sculpture Garden, to which the Committee of 100 has offered comments.  One of the proposals in the Master Plan that is generally supported is the proposed restoration of the interior of the Smithsonian Castle.  To date, there has been no further action on implementation of the Master Plan, given lack of federal appropriations and the Smithsonian’s several competing capital projects.  More important, newly-appointed Smithsonian Secretary Lonnie G. Bunch III has stated that he is not committed to the Master Plan and would undertake a review as needed.

C100 Letter NCPC Smithsonian South Mall Campus Master Plan

Stephen A. Hansen

As a follow-up to that Commission meeting, I write with concern given the number of Commissioner questions raised to which incomplete, incorrect, or no answers were provided by Smithsonian Institution representatives. Each issue, we believe, touches on vital base information needed by the Commission before executing its due diligence in approving/ disapproving the Master Plan. We have outlined these below as brief summaries with recommended “Actions”. We trust this proves helpful in this important process.

C100 Testimony (Partial) Smithsonian Quadrangle

Richard Longstreth

[The Quadrangle Historic District] is an extraordinary ensemble of buildings and landscape, created over a period of nearly a century and a half, from 1846 to 1987. The nomination delineates the many facets of this complex that render it historically significant. Our research draws from a very substantial array of period documents – popular and professional journals, newspapers, and the extensive archives of the Smithsonian – from scholarly studies, and from a firsthand knowledge of architecture, landscape architecture, urbanism, and historic preservation projects across the United States and from many places abroad.

William N. Brown

Although we are supportive of efforts to rehabilitate the Smithsonian Castle and, perhaps, redesign the entrances to the Sackler Gallery, the National Museum of Asian Art and the Ripley Center, we believe that these initiatives can be accomplished without the extreme changes that would removed the custom-designed and compatible Renwick Gates and destroy the Haupt Gardens.
