Near Thurmont in Frederick County, Maryland — The American Northeast (Mid-Atlantic)
Ruins of the Ironmaster’s House
(Climbing among the ruins is dangerous, damages your historic resources and it prohibited.)
One a magnificent house, the ironmaster’s mansion was an imposing structure that gave the furnace manager an overview of the furnace complex. The grandeur of the ironmaster’s house contrasted with the humble stone cottages of the furnace workers and showed the separation of classes of that day.
The wall were stabilized in 1996 so the public could safely see the ruins. The number of chimney stacks stone structures easily suggest the former stature of this massive house.
