About Dumbarton House

Dumbarton House is a historic house museum that interprets the life of Joseph Nourse, the first Register of the Treasury and resident of the house from 1804 to 1813, and Federal period history, including the formation of D.C. as the capital of the United States. The museum has been open since 1932 under the ownership of the National Society of the Colonial Dames of America (NSCDA).  It is the longest running museum in Georgetown, serving the local community and visitors from all over the world for almost a hundred years.
