Carrie Furnace is a derelict former blast furnace located along the Monongahela River in the Pittsburgh area industrial town of Rankin, Pennsylvania. It had formed a part of the Homestead Steel Works. The Carrie Furnaces were built in 1884 and they operated until 1982. During its peak, the site produced 1000 to 1250 tons of iron per day. All that is left of the site are furnaces #6 and #7, which operated from 1907 - 1978, along with the hot metal bridge.
