"Ruin tower and house adjoining other walls" = Carrigogunnell Castle!
Far be it from us at Library Towers to let people rest on their laurels, and as our original fiendish Mwahaha (evil laughter) was finally solved yesterday after 10 months, I had hoped to challenge you today.
All we had as a description was "Ruin tower and house adjoining other walls, people". Had hoped it'd prove a tad challenging, but 'twas not to be. Thanks very much to blackpoolbeach for identifying these ruins as Carrigogunnell (also Carrigogunnel) Castle!
Either way, also like this image for the spooky way that people seem to loom out of the background when you peer into all corners of it really carefully...
