Near Timonium in Baltimore County, Maryland — The American Northeast (Mid-Atlantic)
Northampton Furnace
Built in 1759 by Charles Ridgely (the Elder) of Hampton and two sons, the iron foundry operated for 70 years on Spring Branch of Patterson’s Run. It furnished cannon and shot for the Revolution as well as other supplies: “300 kettles” were ordered by the Council of Safety July 15, 1775. “Premature discharge” of cannon tested in 1780 killed Captain John Fulford and “dreadfully wounded” others. The furnace stack is now submerged near here in Loch Raven.
Erected by Maryland Bicentennial Commission & Maryland Historical Society.
