The king's cave

"This great cave, from which countless smaller ones opened out on every side, wound far underground and had many passages and wide halls; but it was lighter and more wholesome than any goblin-dwelling, and neither so deep nor so dangerous. In fact the subjects of the king mostly lived and hunted in the open woods, and had houses or huts on the ground and in the branches. The beeches were their favorite trees. The king's cave was his palace, and the strong place of his treasure, and the fortress of his people against their enemies." The Hobbit

I just saw the movie and I loved it.
