The Belmont House is interesting as an example of sequential architectural development coincident with the growth and settlement of Washington, D.C.--from the vernacular colonial farmhouse, built for function rather than style, through the Georgian, Federal, and Georgian revival periods. It does not faithfully represent any of these styles, however, and because of this is generally held in rather low regard by architectural historians. It should, therefore, be emphasized that its significance does not lie in its architecture, but in its historical associations, especially its association with the organization whose militancy was indispensable to passage of the 19th amendment.
The Sewall-Belmont House is famous for serving as the headquarters for the National Woman's Party since 1929. Alice Paul founded this organization and is famous for rallying women to support the passage of the 19th amendment and an Equal Rights Amendment.
The house was originally built in 1800 and incorporated a 2-story 1750 house. It was then burned in 1814 and rebuilt in 1820.
