Among dense trees below East Cowes Castle, seen to the east by the rising full moon, there appears to be a succession of steps or terracing in the foreground.
This is among dozens of blue paper studies made in and around East Cowes Castle, presumably in the course of a single visit. For more on the various aspects of the house (demolished in about 1950), and its lost grounds as depicted by Turner, see the Introduction to this subsection, where other moonlit examples are noted.
Blank; there is a hint of the heavy ink on the recto bleeding through.
