Next to the shore at Port Henry is the former Witherbee-Sherman Mining Company headquarters, now occupied by the Moriah town offices, with the local historic society and the Iron Center Museum, sited in a former carriage house. Port Henry, on the shores of Lake Champlain, became a major industrial port in the late 1800s, with blast furnaces, shipping terminals, and railroads, processing and distributing iron from the local mines. The furnaces closed by the late 1930s, and have been removed, leaving a shoreline extended and altered by tailings.
