Get a closer look at trades of the eighteenth century during Newlin’s “History at Work” series. Members of Newlin Grist Mill’s staff, volunteers, and outside artisans demonstrate crafts and illustrate how different trades and skills were integral to life in colonial Pennsylvania and to the operation of the Newlin Grist Mill. These demonstrations take place on the last Saturday of the month from April through October between 10:00 AM and 3:00 PM. “History at Work” is free and open to the public. All age groups are welcome..
