Forget putting up four walls and a roof; these homes use the stony walls of natural and human-made caves to shelter their inhabitants from the storm. Check out these incredible rocky homes, from ancient cave dwelling to modern house, to the buildings that may have inspired J.R.R. Tolkien’s Hobbiton.

There really are some incredible looking homes around the world. Stunning photos in this post.
