Decatur House - Federal-period period-room installations

Decatur House, built in 1818 and located adjacent to Lafayette Square, is a preserved Federal-period rowhouse operated as a historic house museum that presents furnished period rooms interpreting early 19th-century domestic life and social history. The house's curated rooms, exhibits, and interpretive installations document the lives of its inhabitants and the property’s ties to Washington’s early federal-era elite. Decatur House is open for tours and educational programs focused on its architecture, material culture, and historical context.
