Dumbarton House stood witness to the birth of the American Republic as the government settled into the newly established Federal City. Built in 1799, on the heights of Georgetown, Dumbarton House was the home of the first Register of the U.S. Treasury, Joseph Nourse, who resided here with his family and servants — free, indentured, and enslaved — from 1804-1813. Dumbarton House’s period room and rotating exhibitions the stories of the early city of Washington and offers visitors a view of what life was like in the earliest days of our Nation’s Capital.

In 1928, The National Society of The Colonial Dames of America (NSCDA) purchased the property as its national headquarters an opened the museum to the public four years later. As the headquarters of the NSCDA, Dumbarton House shares the stories of women in preservation. The NSCDA, through its Corporate Societies, owns, maintains, or supports over 80 historic sites and collections around the country.
