A very large mill composed of the normal sized 40'X 50-60' mill with a 15'X 35'wing on either side, comprised of the same construction materials; two stories of native limestone under 1.5 stories of brick. Top this off with metal roofing.

The mill was built, according to a local historian, in 1820 when the construction of the Union Canal effectively blocked access to the waters of the Tulpehocken Creek to the old Ansbach Mill immediately behind this mill. This is probably a false statement because of the following: *Update: The Hershberger Mill was built as a house mill. Portions of the house mill and architecture within the stone portion suggest that part of the mill might date into the 18th century. The building behind this mill is not the Anspach Mill, but is believed to be an 18th-century two-story school house constructed by Christ Lutheran Church.

Some millers operating the mill through the years; Edward Good, Michael Hershberger, George Zimmerman, and a Mr. Knabel. The mill is directly opposite the Union Canal Lock # 17. Part of the mill was a residence in the fall of 1987.
