The historic district includes simple popular vernacular architecture derived from the Greek and Gothic Revival styles. One large simple brick building and a deteriorated brick section of another building may have been built by Pennsalt, but otherwise the industrial site has been thoroughly rebuilt to suit the new owner and does not have historic character.

Including various buildings for refining salt and oil, furnaces, chemist, cooper, and carpenter shops, a brick yard, and stables, this area was taken over by Allegheny-Ludlum Steel Corporation in 1967. The company's industrial buildings, where a wide range of chemicals for home and industrial use were produced from 1850 until 1957, were located on adjacent land to the northeast. Eight blocks of densely-built detached houses and row houses are situated on the north side of the Allegheny River approximately 21 miles northeast of Pittsburgh, on flat land between the river and a steep hillside in Harrison Township.

The Pennsalt Historic District is an approximately 8.5-acre area of mid-19th century company housing erected by the Pennsylvania Salt Manufacturing Company beginning in 1850. Portions of the content on this web page were adapted from a copy of the original nomination document that was submitted to the National Park Service.

The Pennsalt Historic District was entered onto the National Register of Historic Places in 1985.
