This is an unfinished watercolour, showing the view looking past the crossing and organ screen into the chancel. The sonorous tonality and bold treatment of Romanesque architecture take up themes that Turner had treated with great force in his exhibited watercolour of 1797, Transept of Ewenny Priory, Glamorganshire (National Museum Wales, Cardiff).1
A similar subject, embarked on about this time and taken closer to completion, is the grand view of the interior of Durham Cathedral (Tate D01101; Turner Bequest XXXVI G).
