Visit the country summer home of the prominent Wister family and discover their contributions to the fields of horticulture, historic preservation, astronomy and American literature. Sally Wister, who lived in the house during the Revolution, kept a dairy of her experience and perspective on the changing nation. Her diary remains in publication today and provides insight into the thoughts of teenagers during this time period. Built in 1744 by wine importer John Wister, Grumblethorpe was originally known as 'John Wister's Big House' because it had multiple stories. Built from native stone quarried on and oak cut from Wister's extensive property, the house is a prime example of domestic Pennsylvania German architecture of the period. Period furnishings and the personal property of the family are on display for visitors to experience. The large gardens surrounding the house have been restored to resemble the gardens as they appeared in the 19th century.
