I built this over a year ago and it has sat on a shelf ever since! Styrofoam, clay and wood construction. 25/28mm. Designed to work with the edges of the table it has a tower that can form a right angle and a tower that fits into the straight section of the wall. Gate opens and even has a locking beam that will keep the barbarians out! I also built a damaged section that can be swapped in in case of siege.
