Mount Washington is a hill in Pittsburgh, on the southern banks of the Monongahela River and Ohio River. In the early history of Pittsburgh, Mount Washington was known as Coal Hill, but Coal Hill was actually on the south bank of the Monongahela River. Easy access to the Pittsburgh coal seam's outcrop near the base of Mount Washington allowed several mines to operate there. Also, rock was quarried from the hill. Gray sandstone, for example, was quarried at Coal Hill for the second Allegheny County Courthouse.
