I know this is a weird question to ask. But I want to know if a gate set-up like what I am about to show you is a thing in real life.
Ugh, yes, so that’s tiny. And it’s just technically half the gate, I suppose, but bear with me. So, there’s the city wall on the left. On the right is the door, or the left of two doors, the hinge which is hidden behind a large stone or brick section, which is kind of an elaborate structure, the point of which is supposed to be that the gates can stay closed, but that people can pass in and out one at a time in the gap between the city wall and the wall of the actual door structure. The green curve there indicates where individuals would walk. Guards could then be posted where those two little circles are, if necessary, because two guys with spears or swords or guns could shoot or stab intruders who had to enter one by one. But at my gate, there’s probably not guards. People can go in and out one at a time and that’s cool.
It’s just a wholesale pouring in of an army, or worse, pouring out, that the gate would need to prevent.
Anyway, some of you are military folks and some of you are medievalists and so I’m hoping you can point me to whether this is a real thing already or if I’m going to have to invent it.
