History and architectural features
Built sometime around 1760, this historic structure is a two-and-one-half-story, five-bay, fieldstone dwelling. It has a two-story, two-bay-by-two-bay limestone extension on the north side, and is an example of Scotch-Irish farmhouse architecture.

William Gass, a fuller who had immigrated from Ireland, built the house circa 1760, and left it to his brother Benjamin. Benjamin's son, Patrick Gass, was born in the house. Patrick later became a soldier and a carpenter and was an important member of the Lewis and Clark Expedition. Although Patrick was in line to inherit the house, it is unclear whether he ever lived in it as the owner.

In 1808, the house was sold to the county for use as an almshouse.
