Drive west on Factory Street/Washinee Street to Mt. Riga. The road to the mountain top generally follows Wachocasttinook Brook. Bear left on Mt. Riga Road at mile 0.7+. The road shortly changes from paved to unpaved. Continue to mile 3.2 where, on the left in the woods, are the remains of a large dam. Two finery forges with helve hammers operated below this dam. At mile 3.5 is the intersection of Mt. Riga Road and Washington Road. Directly west of the intersection is the dam holding South Pond.

Turn left to the small open field. The Riga blast furnace stands about 200 feet down the field to the left. It is the only standing cold-blast furnace remaining in Connecticut.


Mt. Riga had four ponds that fed a single outlet, the Wachocasttinook Brook. The Salmon Fell Kill forms from the Fell Kill (now Wachocasttinook Brook) flowing from South Pond on Mt. Riga.


Water rights to South Pond area first held by Thomas Lamb.

1762 -- Hazeltine, Allen and the Forbes brothers began operation of northwest CTís first blast furnace. Samuel Forbes was the ironmaster. The Salisbury Furnace was 17 miles from the big deposit at Old Hill. Lime for flux was taken from the outcrops of the Stockbridge formation. And wood for charcoal came from Mt. Riga.
