The Barn is located across Walnut Street from the Heller-Wagner Grist Mill and the Miller’s House and was completed in 2005 by the Hellertown Historical Society. Displays include numerous agricultural implements and machinery, blacksmith tools, cabinetmaker tools, and even a wooden sleigh once drawn by horses.

Visitors may also tour The Grist Mill and view the mill’s gear mechanisms, machinery, scale, and mill race. The upper level of the Grist Mill houses an eclectic mix of scenes depicting life in Hellertown’s earlier days. Highlights include The Country Store, The School Room, The Doctor’s Office, The Pharmacy, and various household scenes.
