Valley (aka Hillsview) - Is on a branch off Mill Creek in Ligonier Township. It was built in 1850 by L. C. Hall and
Company. It was a very large furnace being 36' square at the base with a 10' bosh. Coke was burned in piles near the furnace and was used instead of charcoal(s&t). The furnace has a large hole or opening in the upper back side, most probably, to vent the excess flame and heat to boilers for steam power, as this furnace was a hot blast coke furnace not near a
stream(rp). The furnace stands in plain view about 60 feet from the road and has a few of the upper rows of stones missing but is in otherwise good condition. However, trees and brush, growing out of the upper stack, will probably deteriorate the stack if not removed.(rp). (P)(V)(rp-1978,
