St Maurice Forges

Were situated on the river St. Maurice, about nine

miles above Three Rivers, Quebec. Iron ore was discovered on the banks

of the St. Maurice in 1667, but the mines were not systematically worked

until 1733, when a company was formed and forges established. Since that

date and until 1883, under different ownership, they were in active

operation, being the oldest blast-furnace, on the continent of America.
