NOTR door at claw of beliar doesnt open

when i have defeated raven and have the claw of beliar i can't get out !
How do i open the door ?

Im really stuck now

Taken from a N3Burgener's walk-through of the game:

NOTE that for some reason in my gameplay, the door leading into the antechamber
wouldn't open again after I had killed Raven. If this happens to you, you'll
have to do some clipping to get through. Left-Strafe into the corner where the
stone door meets with the stone frame around it, and play around with the turn
keys, left and right. It may take some trial and error, but you should pop over
to the other side, and the door will the open

Hope that helps.

Not familiar with any bug of that sort but unless you're against using the console/cheat commands pressing B-Marvin-B and then K should work.

First of all thanks for answering.
What is b-marvin-b ?
and i don't use cheats….

Behind the altar there should be a button that opens the door.

Indeed the button worked !
Don't know why i didn't find that myself.
Thanks DeepO
