A watercolour drawing of Windsor Castle, showing a view through the Norman Gate, looking west, with the Magazine Tower and Winchester Tower seen in the distance through the archway. A soldier, drawn loosely in pen and ink, is standing on the left, and a man and child are further back. Black ink line and grey wash mount, with a partially erased inscription in brown ink 'By Thos Sandby'. Inscribed on the verso, once in pencil and once in pen and ink, 'Gateway under the Library, Windsor / P. Sandby'.

A finished bodycolour of this view is at the Yale Center for British Art, New Haven (B1975.4.1846), inscribed with the date 1767. It may form part of a group with works with the same date at the Museum of New Zealand Te Papa Tongarewa, Wellington and the Courtauld Gallery, London. Another watercolour version of the same view dated 1785 is at Leicestershire Museums and Art Galleries. An outline etching of the same view was included in the series of views of Windsor, 1780, which possibly used a pencil drawing in the Staatliche Museen Greiz (E 473) as its model.
