This is a project that has been going for the last 3 months. I've looked at scaling and recreating the Iconic castle from Game of Thrones (Highgarden) quite literally almost merlon for merlon. I'm still working on angles since the towers on the west side of the castle (facing the 3 main towers on the northern side) should technically be on an angle.
So far I have the rough outlines of the main castle walls, but I still have a lot to do. Next update may possibly have the towers on the correctly positioned angle, and the curtain walls surrounding the main fort.
