Here are the two wall sections I’ve built for the display. The ends are CCC compliant although the middle section on each is one brick higher for visual interest. I also tried to make the walls “interesting” with small windows as arrow slits and some variety in stonework, etc. The one wall also has some wood battlements as a temporary fix for previous damage sustained. The back sides are pretty bland and I did add one orange brick at the very bottom corner of each for easy identification.
