SAAM describes itself as being "dedicated to collecting, understanding, and enjoying American art. The museum celebrates the extraordinary creativity of artists whose works reflect the American experience and global connections." Galleries and public spaces The American Art's main building contains expanded permanent-collection galleries and public spaces. The museum has two innovative public spaces. The Luce Foundation Center for American Art is a visible art storage and study center, which allows visitors to browse more than 3,300 works of the collection. The Lunder Conservation Center is "the first art conservation facility to allow the public permanent behind-the-scenes views of the preservation work of museums". The Luce Foundation Center for American Art The Luce Foundation Center, which opened in July 2000, is the first visible art storage and study center in Washington, D.C. and the fourth center to bear the Luce Family name. It has 20,400 square feet on the third and fourth floors of American Art Museum. It presents more than 3,300 objects in 64 secure glass cases, which quadruples the number of artworks from the permanent collection on public view. The purpose of open storage is to allow patrons to view various niche art that is usually not part of a main exhibition or gala special. The Luce Foundation Center features paintings densely hung on screens; sculptures; crafts and objects by folk and self-taught artists arranged on shelves. Large-scale sculptures are installed on the first floor. The center has John Gellatly's European collection of decorative arts. Lunder Conservation Center The Lunder Conservation Center, which opened in July 2000, is the first art conservation facility that allows the public permanent behind-the-scenes views of preservation work. Conservation staff are visible to the public through floor-to-ceiling glass walls that allow visitors to see firsthand all the techniques which conservators use to examine, treat, and preserve artworks. The Lunder Center has five conservation laboratories and studios equipped to treat paintings, prints, drawings, photographs, sculptures, folk art objects, contemporary crafts, decorative arts, and frames. The Center uses various specialized and esoteric tools, such as hygrothermographs, to maintain optimal temperature and humidity to preserve works of art.
