I really enjoyed this MOC when I noticed it in the LEGO Literature pool on Flickr recently, though I’ll admit it’s been a few years since I’ve read Sir Gawain and the Green Knight. (Pronounced Gah’-win not Guh – Wayne).
The doors are well done with the recessed 2×2 spinner plate bottom (which, incidentally, seems to get used more decoratively these days. Was it all due to the official Taj Mahal set? Or had AFOLs been doing this sort of thing sooner?)
While you don’t see an entire castle here, what you do see is very believable. And the photo came out great!
