The Monocacy Creek provided water to wash the hides before, during and after tanning. The adjacent butchery provided a large supply of animal hides. The forests surrounding Bethlehem provided large quantities of oak and hemlock trees to supply the bark which produced the tannic acid used in the tanning process. Bethlehem’s first tannery was a small log structure built in 1743 which stood on the opposite side of the raceway. The second, larger tannery was constructed in 1761. Here Moravian tanners worked about 3,000 hides each year. During the years of the American Revolution, their output rose to about 6,000 hides annually to help supply leather to the Continental Army. Tanning ended in Bethlehem in 1873. After that time, the tannery was converted into apartments and eventually housed other businesses such as a commercial laundry in the 1900s. The building was restored and opened to the public as a museum in 1971.
