Built 1801 to 1807, Riversdale is a two-story, hip-roof late-Georgian mansion of stuccoed brick, with flanking hyphens and wings, and particularly fine interior plaster detail. Standing next to the mansion is a two-story gable-roof dependency building, also of stuccoed brick. The mansion was designed by Washington architect/ builder William Lovering for Flemish aristocrat Henri Joseph Stier, and finished by Stier’s daughter, Rosalie, and her husband, George Calvert. Certain elements were inspired by the Stiers’ Belgian residence, Château du Mick. It was the residence of agriculturalist Charles Benedict Calvert, founder of Maryland Agricultural College, now the University of Maryland. Listed in the National Register in 1973, Riversdale became a National Historic Landmark in 1997.
Dating from the 19th century, the Calvert Family Cemetery includes the graves of George and Rosalie Calvert, four infant children, Charles Benedict Calvert and his infant son. The Calvert family occupied Riversdale plantation from 1803 to 1887. Charles Benedict Calvert was a major figure in the establishment of the U.S. Department of Agriculture and the Maryland Agricultural College, now the University of Maryland.
