[1] The Old Stone Blacksmith Shop stands in a rural area of Cornwall, on the west side of Vermont Route 30 about midway between its junctions with Ridge and Robbins Roads.

It is a single-story structure, fashioned out of irregularly coursed limestone and covered by a gabled roof.

It is set into a sharp rise, so its front is fully exposed, but its rear wall is almost completely below grade.

The front facade has a horizontally rectangular window at the center, and a two-leaf bay door to its right, fastened with wrought iron strap hinges.

[2] The shop has traditionally been given an early construction date of 1791, the year Thomas Pritchard purchased the property.
