The Herr family barn is a rather large Sweitzer (or Swisser) style bank barn with a forebay to the south side. It measures 114’ x 46’ with several sheds added over a century and three quarters, The main structure was built around 1850 on a limestone foundation whose stones were likely taken from a small quarry that existed to the west of the barn. The upper structure is framed with five “bents” of post and beam timbers held together with wooden pegs or “trunnels”.
There is evidence that some frame members may have been salvaged from an earlier house or barn. Several floor beams indicate that they were sawn from logs floated from northern Pennsylvania as part of a timber raft on the Susquehanna River.
The lower level houses a collection of tools and farm equipment which would have been used in the late 1800’s and early 1900’s,
The upper level consists of the threshing floor, hay and straw mows and the granary. Larger pieces of equipment can be viewed from the open doors at the north side. The Tobacco Shed, 36’ x 64’, was rebuilt in 1930 after a windstorm blew down the original. Tools and equipment used in growing, harvesting, curing and marketing of Tobacco can be seen here. The original lower level stripping room has been re-created on the main floor for the safety of visitors.
