It's an outside level. And it looks to be some sort of hub.

I get the Eagle looks very American-y, but I kind of don't see how it's a fourth of July thing. Say it's meant to be used at start for fireworks, that building isn't what our building looks like. I don't think enough evidence proves that it's 4th related.(other than it using the dark tiles)


plus I know i've seen that eagle on era before. Can't place my tongue on it... brain fart.
