"Scott's son in law John Gibson Lockhart took the artist J. M. W. Turner to Craignethan in September 1834, approaching it from the north-east via the Nethan Gorge.The "Scottish Tourist" of 1836 also describes the approach from the Nethan Gorge to the castle "standing upon a vast rock overhanging the Nethan", adding that from its proximity to Lanark, Bothwell Bridge and Drumclog, "there is no doubt that it is the prototype of the "Castle of Tillietudlem"".
