untonuggan | Post-apocalyptic dystopia remnants

I just had to share this photo I took along a walk near Washington, DC. I'm really not sure what it is, but my friend and I both agreed that it looks as though when you enter it there should be a loading screen and then a dungeon crawl to a boss with plenty of phat lewt. Or something.

In reality, I'm pretty sure you'd drown if you tried that.

But it's tres cool! Especially because there's a large road that passes nearby and you get lots of car whooshing noises when you look at it.

Edit: Problem resolved! Apparently it is the remains of an old pump house,and the area used to be called Pump House Falls.
