This is the 125,000 piece LEGO Game Of Thrones Red Keep built by LEGOmaniac Claus-Marc Hahn. It uses motors powered by four LEGO Mindstorms EV3 controllers to spin and raise/lower the towers, just like in the opening credits of the show. How about that! Just a hundred more lifetimes and Claus-Marc could recreate the entire opening. Obviously, I'd suggest making a deal with a witch for your soul.
Keep going for a video tour of the keep, including its inner workings.
Thanks to GD, who was really hoping to see a couple LEGO dragons flying around above the keep.
