Christmas in C.S. Lewis' "The Last Battle"

 Tirian looked and saw the queerest and most ridiculous thing you can imagine. Only a few yards away, clear to be seen in the sunlight, there stood up a rough wooden door and, round it, the framework of the doorway: nothing else, no walls, no roof. He walked toward it, bewildered, and the others followed, watching to see what he would do. He walked round to the other side of the door. But it looked just the same from the other side: he was still in the open air, on a summer morning. The door was simply standing up by itself as if it had grown there like a tree. “Fair Sir,” said Tirian to the High King, “this is a great marvel.” “It is the door you came through with that Calormene five minutes ago,” said Peter smiling. “But did I not come in out of the wood into the stable? Whereas this seems to be a door leading from nowhere to nowhere.” “It looks like that if you walk round it,” said Peter. “But put your eye to that place where there is a crack between two of the planks and look through.”. . . . 

He looked round again and could hardly believe his eyes. There was the blue sky overhead, and grassy country spreading as far as he could see in every direction, and his new friends all round him laughing. “It seems, then,” said Tirian, smiling himself, “that the stable seen from within and the stable seen from without are two different places.” “Yes,” said the Lord Digory. “Its inside is bigger than its outside.” “Yes,” said Queen Lucy. “In our world too, a stable once had something inside it that was bigger than our whole world.” (2008-10-29).
