Washington Navy Yard
Following the War of 1812, the Washington Navy Yard never regained its prominence as a shipbuilding facility. The waters of the Anacostia River were too shallow to accommodate larger vessels, and the Yard was deemed too inaccessible to the open sea. Thus came a shift to what was to be the character of the Yard for more than a century: ordnance and technology. The Yard possessed one of the earliest steam engines in the United States, and was used to manufacture anchors, chain, and steam engines for vessels of war.
