Pennypacker Mills

Location: Schwenksville
Built: 1720

The estate known as Pennypacker Mills served as an encampment site for the Continental Army before and after the Battle of Germantown. George Washington used the Pennypacker Mansion as his headquarters during both encampments.


In September 1777, with the Continental Army struggling to gain the upper hand in the fight against the British, George Washington led his troops into rural Montgomery County. For three days, the Army encamped on the grounds surrounding a local mill owned by Samuel Pennypacker. 

Washington marched his troops out on September 29 as they prepared to once again engage the enemy. Days later the two armies would clash near Germantown. The result was a disheartening defeat for the Americans, and the Continental Army once again retreated back to Montgomery County, setting up camp once again at Pennypacker Mills from October 4 through 8 before heading east once again. 

During the Army's stay, George Washington is said to have used the mansion house as his headquarters. Though the house underwent an expansion and enlargement in 1901, the room where George Washington slept remains and is a highlight of house tours. 

Today the mansion houses the personal collection of former Pennsylvania Governor Samuel W. Pennypacker, who served as Pennsylvania's chief executive from 1903 to 1907. Pennypacker was an avid collector of American historical artifacts, including some dating back to the Revolution. 

Guided tours are available Tuesday through Saturday, 10 a.m. to 4 p.m., and Sundays from 1 to 4 p.m. Tours take approximately one hour with the last tour leaving at 3 p.m.

Admission is free though a donation of $2 per person is suggested.
