Built ca. 1796, the Adelphi Mill is Prince George's County's only surviving historic mill. It is the oldest and largest mill in the Washington area. The Scholfield brothers built the mill in 1796, and it was later owned and operated by George Washington Riggs. The two-story, rustic stone building features a pine interior with hardwood floors and is situated in a lovely park setting. The Adelphi Mill is located on the Northwest Branch of the Anacostia River, within minutes of the University of Maryland, inside the Capital Beltway.
