the Smithsonian American Art Museum in October 2000 so that the museum and its traveling exhibitions could benefit from the Smithsonian's brand recognition. After renovations were underway, the plans were broadened in an effort to restore much of the building's original elegance. Many of the building's exceptional architectural features were restored: porticos modeled after the Parthenon in Athens, a curving double staircase, colonnades, vaulted galleries, large windows, and skylights as long as a city block. New features added to the building included the Lunder Conservation Center, the Luce Foundation Center for American Art, Nan Tucker McEvoy Auditorium, and the Robert and Arlene Kogod Courtyard. Meanwhile, the museum's offices, library, and storage were moved to the nearby Victor Building, freeing up valuable space and allowing the museum to display four times as many artworks as before. The renovation ultimately took six years and $283 million. The museum and the National Portrait Gallery reopened their combined building, renamed as the Donald W. Reynolds Center for American Art and Portraiture, on July 1, 2006. Affiliated museums National Portrait Gallery The Smithsonian American Art Museum shares the historic Old Patent Office building with the National Portrait Gallery, another Smithsonian museum. Although the two museums' names have not changed, they are collectively known as the Donald W. Reynolds Center for American Art and Portraiture. Renwick Gallery Also under the auspices of the Smithsonian American Art Museum, the Renwick Gallery is a smaller, historic building on Pennsylvania Avenue across the street from the White House. The building originally housed the collection of the Corcoran Gallery of Art. In addition to displaying a large collection of American contemporary craft, several hundred paintings from the museum's permanent collection — hung salon style: one-atop-another and side-by-side — are featured in special installations in the Grand Salon.
