It's a little chapel in the mountain ranges in Wyoming. It's called the Chapel of Transfiguration, and just looks like a little log cabin chapel on the outside. It's very charming in that respect. The inside, though, is beautiful: the back wall behind the altar is made up of a huge picture window looking over the gorgeous mountain range.

I think it's one of the most phenomenal places a couple could be married.

Update: I know you're looking for cool and unique places, but I'm from Michigan and haven't seen many places that really wow me for a wedding locale. I sincerely do recommend that you look up the chapel I mentioned, because I think it's gorgeous and unique.
