The Girl in the Forbidden Tower

by Sofia
(Stockholm)

I'm looking for the title of a horror movie about a young couple who just got married and move into a house that looks like a castle. They were told not to go into the room in the tower, but the wife just couldn't resist going in there and when she opened the door she was surrounded by mirrors.

She never told her husband about this, and every day she could hear a little girl crying.

The movie ends when the couple sees the little girl, and the wife jumps out the window and the guy jumps out after her.

Is anyone familiar with this movie?
