while playing a single player game a week ago, while i was forced to be bored and completely lonely without EMC i found this. it was in site of a village, just chillin. i had never ever seen one before, in all my minecraft days, never once spotted one.i was told it has something to do with the eyes of ender, which i have never seen one (without creative mode) of course.. i looked it up on the wiki as well, but i still don't understand where this building comes into play.i'm sure someone knows. is that what this is for? or is it something else?
