The last nineteenth-century carriage shop preserved in the United States, Heiss Buggy Works operated from 1889 to 1920 and is now an industrial museum. The centerpiece is the coachworks, complete with original tools and equipment. Banked into the hill on the gable end to provide a ramp for vehicles, the L-shaped building was constructed of unpainted board and batten. On the ground floor, a forge and blacksmith's shop produced the vehicles' metal frames, while upstairs, carpenters made the wooden bodies, painted them in the trim shop, and fitted the buggy tops sewn in the stitching room. Nearby on the south side of Quarry Road is the repository and carriage house (1895) where vehicles were displayed and stored. The deteriorating building was reconstructed in 1993 and now exhibits buggies, carriages and sleighs, a mail truck, and a Conestoga wagon. Also open to the public is the clapboarded William A. Heiss House (1870) at 598 Green Street, with its period furnishings. At 5th and Green streets, a brick addition to a log house shows halftimber framing that is evidence of German construction systems reaching this area.
