In this watercolour, based on a pencil drawing (Tate D00695; Turner Bequest XXVIII J), Turner achieves a tonal unity and continuity that are, perhaps, new, and which make it difficult to date precisely. It marks a departure from the striated, jerky application of washes, reflecting the influence of Edward Dayes (1763–1804), in the watercolours that he had been producing in 1793, and could date from as late as early 1795; the sky in particular seems to suggest that date. But it was most likely executed in the latter part of 1794. Another technically sophisticated watercolour of a London subject of about this time is Tate D00684 (Turner Bequest XXVII W).
The sheet was formerly folded laterally approximately 10 mm above the lower edge.
