Holt House is an historic house, located on the grounds of the National Zoo, and probably built before 1814. It is one of the most important examples of early Neoclassical architecture in Washington, D.C., and was one of the major houses in the new Federal City when it was built. Its caretaker has been the Smithsonian Institution since 1889, and is the oldest building under the Smithsonian's auspices, but has been left vacant since the 1980s. It was listed in the D.C. Inventory of Historic Sites in 1964 and was placed on the National Register of Historic Places on April 24, 1973.
