Grumblethorpe

Germantown 1744

German immigrant John Wister (Johannes Wüster, 1705-1789) built this house in 1744 as a family country home outside of Philadelphia. Constructed of local Wissahickon schist and oak timbers hewn from Wister’s woods, the house is a prime example of Germantown architecture of the period.

Notable features include the stone coursing of the facade, front and rear balconies and the double front entrances. The property included a farm, gardens, and orchards with fruit trees to supplement John’s wine importing business.

Known through-out the 18th century as John Wister’s Big House, Grumblethorpe was just one of John’s many properties in Philadelphia and Lancaster. Intended as a summer retreat, the house provided a refuge for the family from the humid Philadelphia summers, and in 1793, the family stayed in Germantown to avoid the yellow fever epidemic.

This house was also taken over by the British and used as one of its headquarters during the Battle of Germantown in October 1777, as John Wister was staying in his Market Street home in Philadelphia and John’s son Daniel and his family had fled to a relative’s house in what is now Lower Gwynedd.

In the early 19th century, Charles Jones Wister Sr., John’s grandson, an astronomer, horticulturalist and inventor, made this Germantown house the permanent family home. He modified the front and back facades to Federal era architectural trends, created additions, and even had an observatory built. It was Charles Sr. who gave the house its new name: Grumblethorpe.

Since acquiring the building in 1941, PhilaLandmarks has restored and furnished the house and cultivated the gardens to reflect the interests and tastes of various generations of Wisters. Coming up in the later half of 2023 and 2024, we will be embarking on further restoration projects at this unique historic property
