History buffs and curious visitors alike will have the rare opportunity to experience early American industry in action during the upcoming Open House at the Bowmansville Roller Mill on May 17, hosted by the Historic Preservation Trust of Lancaster County.

Built in 1850—and with roots going back to 1737, even before George Washington was born—the Bowmansville Roller Mill stands as one of Lancaster County’s last two fully functional water-powered mills. On May 17, guests will not only tour this remarkable structure but also witness live milling and sawmill demonstrations, offering an authentic glimpse into 19th-century life.
