I'm not asking for this for myself, but I do know there are people who like fortifications and such, but what do you do with the creek that runs thru your walled village? How about a water wall that spans it but keeps the village enclosed?
The wall runs low to the water with 3 pieces: a left side, a right side, and a center piece (top part of the curve) that you can use to span any size creek or stream. Example image:

I thought maybe someone might want to play with this idea, can make wood and stone options. Just a thought! :)
