I have something that's been bothering me.

How do these doors open? I've been looking at these gates, and it doesn't seem they open in and out, like a set of double doors, especially if you look at the bars at the very top (and if they did, how the heck is my character strong enough to push them? They're huge!), but it doesn't seem possible to go up and down either.

A lot of the "loading screen" doors don't seem to have a logical way of opening, so I'd figure I'd ask the experts.
