Pennypacker Mills

Pennypacker Mills is a Colonial Revival mansion situated along Perkiomen Creek with roughly 170 acres of farmland surrounding the property. The structures and grounds showcase both the agricultural operations and domestic life of a prosperous family during the 1800s.

George Washington established his headquarters here in 1777 before the Battle of Germantown and used the site as a field hospital. This connection to the Revolutionary War makes it a witness to critical moments in American military history.

The mansion holds an extensive collection of antiques and manuscripts assembled by Pennsylvania Governor Samuel Pennypacker in the early 1900s. These objects reflect the refined taste of a wealthy family and their deep connection to the region's past.

The property is open to visitors several days per week, though hours vary between weekdays and weekends. It is helpful to confirm current hours ahead of time to ensure your visit aligns with when the site is accessible.

The same family held ownership of the property for eight generations, from the initial purchase in the 1700s through much of the 1900s. This extraordinarily long continuous ownership is remarkably rare for large estates in the region.
