Black Knights' Prison Fortress by J.J.J Kytzoin, on Flickr
The Black Knights keep their most dangerous captured enemies and daily headaches locked here. Not many have escaped this heavily guarded fortress.
This was much fun but wouldn't be sure I used any that interesting techniques. Was quick built too. Nevertheless I think managed to make it look quite classic, and actually every single grey and brown brick are older shade. Had to rely on a few wall panels though, which I don't like too much
