Slickville Historic District

Slickville is a company mining village in northern Salem Township, Westmoreland County, built by the Cambria Steel Company in 1916 and 1917 to serve Slick Mine No. 91, a captive drift mine supplying high-grade coking coal to the Rosedale by-product coke plant near Johnstown. The district includes 77 miners' houses and six managers' houses of vernacular company design, along with a company store, church, school, and four surviving brick mine buildings, including the motor barn, the 1918 power house, and the lamp house. Midvale Steel & Ordnance acquired the property in 1919 and Bethlehem Steel took over in 1923, which later merged the four drift entries into one mine. Production peaked in the late 1920s and ended in October 1943 when the seam was exhausted. The district is valued for its intact layout, its surviving mine structures, and buried archaeological remains of the extraction operations, which together document how captive coal mining and company housing worked in western Pennsylvania.
