About Dumbarton House
Dumbarton House is the only property fully owned and operated by The NSCDA. Built in 1799, this Federal period house in Washington, D.C.’s Georgetown neighborhood includes a museum, event space, and beautiful grounds. A few visionary Dames bought Dumbarton House in 1928, and a select group of steadfast Dames currently serve in an advisory capacity on one of NSCDA’s standing committees, known as the Dumbarton House Board, to help steward the historic site and house museum.
Through the interpretation of its historic site and collections, Dumbarton House Museum promotes the understanding of historic preservation and of the early history of our nation, so that the lives and ideals of early Americans inspire current and future generations.
Details of our organization and achievements are presented in our annual reports.
