MONARCH, PA

The Connellsville Coke and Iron Co. built the Monarch "patch" in 1886, also known as Leisenring No. 3. The plant consisted of a vertical shaft down into the Pittsburgh coal seam, and beehive coke ovens. H.C. Frick Coke Co. took over in 1890, and the mine was idled in 1926. During World War 2 the Leisenring No. 3 mine was reactivated, and the coal was transported many miles underground to the Monongahela River on the Colonial Beltline. The mine was abandoned once and for all in 1961.
