The Wedge

New Castle County · dedicated 1932 · 1100 Nottingham Road, Newark

Created from the difficulty in surveying the twelve-mile circle tangent point and the Tangent Line defined by Charles Mason and Jeremiah Dixon, this land between the State of Maryland and the Delaware curve is a wedge-shaped tract that was claimed by Pennsylvania but governed by Delaware for more than a century. A joint commission appointed in 1889 from both states awarded it to Delaware. This decision was ratified by Pennsylvania in 1897, with Delaware and the United States Congress following suit in 1921.
