A photo tour of the Pennsalt Historic District, located in Natrona, Pennsylvania.
The brooding grey sky complements the crumbling, soot-covered village of Natrona. The Pennsalt Historic District is what remains of the original Pennsalt company town. The oldest houses were built in 1850. Natrona, located about twenty miles northeast of Pittsburgh, is one of the most sorely neglected historic districts in the region, and maybe the country.
