Green Spring Mill, located in northwestern Frederick County near the city of Winchester, is one of the only extant early-19th century water-powered gristmills in the region. The property includes the mill, with its associated pond and dam, all constructed ca. 1801, and two additional contributing buildings, the Miller’s House (ca. 1900) and a bank barn (ca. 1900). While the mill was built in 1801, the community it served can be traced to the German, Irish, Scots, and English settlers who migrated to the area in the mid-1700s from the northeastern parts of the U.S. in search of land and religious freedom. During its years of operation in the 19th century, Green Spring Mill provided local farmers year-round access to running water, which made milling possible regardless of weather conditions. After serving the area as a country store for decades, Green Spring Mill closed in 2010.
