The main sketch on this page depicts the southern (inner) façade of the Porta Pinciana, a gate in the Aurelian Walls to the south of the gardens of the Villa Borghese. Unusually Turner has supplemented his pencil drawing with touches of red chalk. Further use of chalk can also be found on folio 45 verso (D15381).
There is an additional view on this page, drawn with the sketchbook held vertically along the top edge. The subject, which appears to be a palace or villa, is currently identified although a further sketch inscribed ‘Ville Este’ appears on folio 71 (D15431; Turner Bequest CLXXXII 72).
