A watercolour drawing of the Curfew Tower and the Horseshoe Cloister. In the background at the centre is the Curfew Tower. In the foreground, in a courtyard bordered by a low brick wall and a wooden portico, several stonemasons are at work. Mounted on a yellow, green, black and grey wash line bordered mount of a type associated with drawings from the collection of Sir Joseph Banks. Inscribed on the verso in pencil, possibly in the artist's hand, 'Windsor. View of Julius Caesar's Tower from the West end of St George's Chappel'.

As with many watercolours from the Banks collection, there is a related bodycolour of the same view, in this case dated 1768 (with Leggatt, 1933). The same view appeared in an engraving published in 1777. One of the stonemasons in the foreground appears in a wash drawing in the Royal Collection (RCIN 932457), apparently a study.

The houses in the Horseshoe Cloister, as today, provided accommodation for the choristers and layclerks of St George's Chapel. In the eighteenth century it was known as the Singing Men's Cloister. The walls of the buildings, built around 1480 were very varied in structure and composition. The pitched roofed house in this drawing covers the Chapter Library and was originally built as the Vicars' Hall. The Curfew Tower, originally known as the Clewer Tower, has been the belfry of St George's Chapel since about 1475. It was known as the Julius Caesar Tower at this date. From 1870 the Cloister was substantially rebuilt to the designs of George Gilbert Scott.
