The Dual State Monument was listed on the National Register of Historic Places. Also known as the Donaghey Monument, it was built in 1931 on the Arkansas-Louisiana state line to commemorate the centennial anniversary of the establishment of the boundary between the two states. It is also a memorial to the birthplace of George Washington Donaghey, governor of Arkansas between 1909 and 1913, who had the memorial constructed and was born about one mile south of the border.
