A bodycolour drawing of the Round Tower and the Devil's Tower (Edward III Tower), seen from the Black Rod. In the foreground, a soldier is lying asleep on a low brick wall. Another soldier is flirting with a woman, surrounded by children and a dog. A child is playing with a hoop on the right. The Round Tower is scaffolded, and the Royal Standard is flying.

There is a watercolour of a similar view in the Royal Collection (RCIN 914565), that like other watercolours of the Castle by Sandby has a related work in bodycolour that belonged to Sir Joseph Banks (sale, Christie's, 23 May 1876, lot 22), in this instance dated about 1767 (National Gallery of Melbourne (Felton Bequest 1922, acc. no. 1260/3). A drawing of the right half of the view is also in the Royal Collection (RCIN 914561).

The Edward III Tower was formerly known as the Devil's Tower or the Maids of Honour Tower as it was used in the eighteenth century by the ladies in attendance on the Royal Family. The Round Tower was raised and remodelled by Sir Jeffry Wyatville in the nineteenth century, and the cottages around the Black Rod were removed.
