The Mt. Riga furnace produced all of the iron used in the building of the U.S.S. Constitution, as well as supplying iron to the Springfield and Harper's Ferry Arsenals for gun manufacture. The furnace was shut down in 1856. It is the only standing cold-blast furnace remaining in Connecticut. The oldest remaining blast furnace in Connecticut; some restoration was done in the late 1930's as well as more recently.
