The design of a room does not end with the objects placed inside of it. The wall décor sets the mood, and Henry Francis du Pont was not one to overlook such an important detail.
In the wing added to Winterthur in 1931, the dimensions of one room were decided by the span of hand-painted Chinese wallpaper that du Pont had purchased. Painted in the late 1770s, the paper reveals scenes of high hills and lakes, people, animals, and houses. The walls and ceiling were built so that none of the paper needed to be cut away.
