I don't remember if this had a portcullis or not. Some still did and some didn't. But I did bravely open that little door on the side, on the right there.
It had the mechanism by which the door was opened, or at least unlocked. I really like it.
But even more than big gates into giant walls, I'm intrigued by little doors in obscure corners.
Those were all at Leeds Castle, which isn't in or near Leeds.
