Constructed of native limestone, the two-story structure is an example of
a late 18th and early 19th century farmhouse built in this region.
German-born Johan Michael Heller, “Alt Vater”
like most immigrant Germans arriving in Pennsylvania, was quick to
understand the value of the land he purchased because of its rich
natural resources: limestone, a natural resource in Saucon Valley
which afforded a permanent building material and, once “burned,” in
limekilns, enabled powdered limestone to enrich the soil. The forested
region supplied settlers with a ready supply of lumber and fuel.
