Description 

The Illinois Iron Furnace is the only remaining iron furnace structure in the state of Illinois. Iron was manufactured at the Illinois Furnace by the charcoal blast method. The furnace was built on a dry laid limestone foundation. The exterior of the furnace was manufactured of large limestone blocks quarried near the town of Cave-In-Rock. The interior wall, or lining, was constructed of firebrick from Pennsylvania. The space between the interior and exterior walls was filled with sandstone. Wrought iron binders were placed through the stonework and tightened to secure the walls. All of the stonework was dry laid to allow for expansion when the furnace was in blast.
