Battery Kemble Park is a park in Northwest Washington D.C., administered by the National Park Service. Battery Kemble was a Union Army defensive site during the Civil War. The battery was located on Ridge Road, and included two 100-pound Parrott rifles, placed in such a way as to sweep Chain Bridge, Aqueduct Bridge, and Virginia beyond. Today, the parapet and gun positions are fairly well preserved and remain visible. The park is located south of Nebraska Avenue along Maddox Branch.
