History and architectural features
This mill was built in 1793 by Michael and Chatharina Gunkle. It is a $2 1/2$-story, banked stone structure with a gable roof. Also located on the property are a contributing $2 1/2$-story, stuccoed stone miller's house, a one-story stone spring house, a one-story stone smokehouse, and a one-story stone carriage house.

Gunkle was a German immigrant from Philadelphia who purchased 974 acre in 1792 in East Whiteland, where he constructed and operated the gristmill, along with a saw mill and a fulling mill.

By 1872 the mill processed 1800 ST of flour, feed, corn, and oats yearly. At the peak of its productivity, the mill ran 18 hours a day. The mill remained in continuous operation into the 1940s.

The Gunkle Spring Mill was added to the National Register of Historic Places on December 14, 1978. It is owned and maintained by the East Whiteland Township Historical Commission.
