A pencil drawing of the houses at the back of St George's Chapel, Windsor Castle. Inscribed below: T. Mackenzie 1809, back of St. George's Chapel Windsor, and on the verso: Windsor 1809.

The drawing has been attributed to Frederick Mackenzie, a topographical and architectural draughtsman who worked with Auguste Pugin and John Nash, although it may be by another unrecorded T. Mackenzie. The houses at the back of St George's Chapel, Denton's Commons, were removed in 1859 so the drawing provides a record of the appearance of the houses in the early 19th century.
