| Description | An embrasure or arrow slit in the outer wall of the upstairs ballroom. Probably a feature of an earlier incarnation of the section, or a conceit in renovation. Either way the interior light shows warm from lamps while the outside light is bluer. The plaster is all the same colour. |
