Gunkle Spring Mill is a nationally registered historical resource.
Michael Gunkle built Spring Mill, his first mill, in 1793. The structure
represents post-Revolutionary development in the Great Valley. During
this period, trails became wagon roads - then turnpikes - as stone
houses, manors and stone barns began to replace earlier log structures
because of increasing affluence.
By 1872 the mill processed
1,800 tons of flour, feed, corn and oats yearly. At the peak of its
productivity, the mill ran 18 hours a day. Today the land and
residential areas on Michael Gunkle's original property are still called
Spring Mill Farms.
