Company, Bluestone quarry, sand plant, brickworks, ice plant, woolen mill, Bowest rail yards and several mines and coke oven sites including Hill Farm, Ferguson, Atlas, Mahoning, Watt, and Uniondale. Several of these oven sites still exist.

A quote from Dunbar: the Furnace Town book sums up the significance of the Dunbar industry as it relates to the Pittsburgh area. "For years, Dunbar's iron industry must have been an amazement to Pittsburgh industrialists. Here, iron was made with coke on a continuous basis since 1854. Pittsburgh did not have a successful iron furnace until 1859; for they had no local iron and they encountered problems with their large capacity furnace, which Dunbar had seemingly solved." Dunbar, as part of the Connellsville Coke Region, which extended from Latrobe to the south of Fairchance, was vital to the development of steel in Pittsburgh. In addition, at the height of the coke era in 1899, there were over 19,900 coke ovens in Fayette County. All but fifty of these ovens were the beehive-type coke oven. Those other fifty were the Semet-Solvay byproduct ovens located in Dunbar. These byproduct ovens were the first ones in the United States!

While the industry is gone and the population has decreased, Dunbar continues to exist along the banks of the nationally known Dunbar Creek trout stream, a testament to the proud residents who still call Dunbar home. Through the efforts of the Dunbar Historical Society, the history of Dunbar will continue to be shared with present and future generations.
