Want to check out Hogwarts?
Look at this big Hogwarts on flickr.com. The outside looks great but the inside is even more detailed. I especially like the round Gryffindor livingroom, the room of Requirement, the lesson where Harry and the other pupils meet their fears, the stairway with the moving portraits. It gives an extra dimension with the green and blue ligths in the castle. Different rooms give you details from different movies. There is one picture with a good overview of the inside of the castle.
