An image of what looks to be the Fortress of Solitude has leaked online from the Man of Steel.
We know from the Man of Steel trailer #3 that the Kryptonians have been on Earth before, and that the Fortress of Solitude is eons old.
It looks as if a Kryptonian vessel crashlands thousands of years ago and Superman discovers it in the movie, becoming his home base.
This looks to be a piece of concept art from the movie, at least that's what we are guessing.
Update: Not concept art, it's from the movie.
Either way, take a look at the Kryptonian ship that becomes the Fortress of Solitude in Man of Steel:
Man of Steel opens June 14th in IMAX 3D directed by Zack Snyder and starring Henry Cavill as Clark Kent/Superman and Michael Shannon as Zod.
