Just a thought .. if it´s okey to toss around wild ideas [?]
As this is a Walled-In-Village, hows about a side-entrance .. as a reroute or detour, you decide. I´d agree about the one lane entry/exit to and from village. A twolane gate could easily dwarf the short pieces of wall.
But if the innermost, slightly crumbeled corner[s] of the wall also had a smallish gate [or an opening] too, just enough for a car to pass. And the Village Square had arcades, so the car passing in and out would run behind them, thus --
With a LC prior entrance to Village you could either choose ´around the square´-mode or ´arcade´-mode. One of them slower perhaps? And if the square was single lane, you could add some pavement and have room for some cafe chairs. The arcade would only need room/depth for a car to pass, and could be made of low-relief two/three storeys buildings ..
Moat .. now that would be an interesting feature .. As I live in a town that has had and still has such. Some three-four hundred years ago [this is europe] most coastal towns were built like fortresses, with thick outer walls for protections. Against the enemy, invasions, gangrene, werewolfs, you name it. Everyone going in or out of town had to pass through the towngates. And on outside the wall was the moats, filled with water. Why? Well, it was thought that if an enemy wanted to invade, he´d had to ´cross the moat´ in some fashion. And doing that he´d be bombarded with boilin oil, rusty nails, rotten vegetables, flying cows [I´ve seen it .. on film. Honest!] Later they were found to be suitable as town sewer, but that´s a different story.
But all walls crumble to dust. And they were also used to fill the moats [and some channels too. That´s a dutch feature!], then they finally put on a blacktop and voilá, the Avenues were born.
