It was unveiled in 1878 to commemorate naval deaths at sea during the Civil War. The base is made of Maine blue granite.  

     At the top of the monument are two classically robed female figures. They represent Grief and History. History holds a tablet that is inscribed: "They died that their country might live." Below them lies a life-sized classical female figure who represents Victory. Below her are the infant Mars, the god of war, and the infant Neptune, god of the sea. Facing the Capitol is another classical figure: Peace. There is a fountain below. Its inscription reads: "In memory of the officers, seamen and marines of the United States Navy who fell in defense of the Union and liberty of their country, 1861-1865."
