Etna, one of the older surviving urban villages in Allegheny County, was originally known as Stewartstown. The village came into being around 1820, in conjuction with a factory producing "scythes and sickles," according to The History of Allegheny County by Thomas Cushing (1885). This factory later became the Spang Steel and Iron Company. The Spang Mansion of circa 1828 still stands on Locust Street in Etna. Etna is a fascinating place to walk around and explore, due to the abundance of very old homes, some perhaps dating to the early or mid 19th century. Many of these homes have been remodeled or covered with aluminum or vinyl siding, which makes it difficult to identify their age. Etna, being a working class type of town, does not have many grand homes. Like neighboring Sharpsburg, it is an excellent and intact example of a 19th century urban industrial village.

My guess is this is one of the older frame houses in the town.
