Finberg dates this drawing, and CCCLXIV-149 which may perhaps show the same castle, to the 1830s; it is apparently a smaller variant of the subject of CCLXIII54 which Finberg assigns to the 1820s. The two studies seem to have been executed at about the same time. The lower bands of blue, red and yellow in this one may in fact form a separate study of sunset sky and sea, intended to be read the other way up. The wiping-out technique in the castle itself suggests an early date, but Turner evidently continued to employ this device, which is characteristic of his experimental watercolours of about 1799, until late in his career. The drawing also has some stylistic affinities with work related to the Little Liber. The view is evidently Welsh, perhaps of Harlech, or as Finberg suggests, Criccieth.

This work is also available as a Polaroid.
