Located in the heart of the Dupont Circle neighborhood, the Historical Society of Washington, D.C. operates its headquarters as a historic house museum and a research library. The Heurich House, the home of German-American brewer Christian Heurich, is an invitation to step into family life at the turn of the 20th century. An intimate period garden park offers the perfect spot for a quiet break. On its third floor, the Historical Society provides access to its strong collection of books, photographs, maps and prints, which document the changing faces of Washington.
