Like Upsala, Grumblethorpe, at Number 526 Main Street, Germantown, opposite Indian Queen Lane, displays ledge-stone walls except for its facade, which is plastered, and it has the same returns of the eaves like a penthouse roof across the gables. This large two and a half story house stands directly on the sidewalk and has areaways at the sunken basement windows like many modern houses. A sturdy chimney at either end and two dormers with segmental topped windows are the features of the roof. The high recessed doorway, with its broad marble lower step in the brick sidewalk, is located so that there are three windows to the left and only two to the right. An interesting feature of the fenestration is the use of wide twelve-paned windows on the first story and of narrower and higher eighteen-paned windows on the second. Again there are shutters on the lower story and blinds above. This variation in the windows of different stories is by no means an uncommon feature of Philadelphia houses, and, as in this instance, often came about as the result of alterations. Grumblethorpe was built in 1744 by John Wister, who came to Philadelphia from Germany in 1727 and developed a large business in cultivating blackberries, making and importing wine in Market Street west of Third. "Wister's Big House" was the first countryseat in Germantown. Originally it differed materially from its present outward appearance. There were no dormers, and the garret was lighted only at the ends. Across the front and sides of the house the second-floor level was marked by a penthouse roof, broken over the entrance by a balcony reached by a door from the second story. To the right of the entrance there were two windows, as at present; to the left there was a smaller door with a window at each side of it. Both doors were divided into upper and lower sections and had side-long seats outside. In the course of repairs and alterations in 1808 the penthouse roof and balcony, also the front seats, were removed, the upper and smaller lower doors were replaced by windows, and the front of the house was pebble dashed. A long wing extends back from the main house, and beyond is a workshop with many old tools and a numerous collection of interesting clocks in various stages of completion. Still farther back is an observatory with its telescope, also a box-bordered formal garden in which still stands a quaint rain gauge. Indoors, the hall and principal rooms are spacious but low studded, with simple white-painted woodwork, and in the kitchen a primitive crane supporting ancient iron pots still remains in the great fireplace. Much fine old furniture, many rare books and numerous curios enhance the interest and beauty of the interiors.
