The Kildow Mill stood on this site, where a grist mill had operated since 1830. The original mill was built at a bend in the Little Youghiogheny River by Murry Thayer for Issac McCarty, who owned several hundred acres in the area. Powered by a water wheel using river water, the mill was later also used by Thayer as a saw mill, and lumber from it was used to build several nearby houses. For a short time, the area around the mill was known as "slab town." In 1855, McCarty sold his land, including the mill, and moved West. A number of later owners improved the building to its final size and appearance. In 1877, Peter Martin bought the mill and installed a steam engine to power it. Its final owner was Michael Kildow, from whom it took the name Kildow's Mill. The mill building was torn down in the early 1950's.
