This sketch within the precincts of Edinburgh Castle, made with the sketchbook inverted, looks south with the Half Moon Battery wall to the left and the Royal Palace straight ahead. The drawing is similar, though more finished and from a slightly different angle, to a sketch on folio 41 verso (D17575). Between the cannon and the flag-pole are a few steps, and it was from here that Turner sketched the view north-east on folio 38 verso (D17569).
This sketch is one of several made in connection to the procession to the castle with the Regalia of Scotland on 22 August 1822 (see folio 36 verso; D17565). On that occasion the King stood on a spot close to where this sketch was made to wave to the crowds assembled below.
