"The Horse And His Boy" Inspired by Turkey's Fairy Chimneys?

I always thought it would be cool to carve out a home in one of the Fairy Chimneys in Turkey. I'm convinced that CS Lewis was inspired by these when he wrote of the "tombs" in The Horse And His Boy calling them, "...great masses of mouldering stone shaped like gigantic beehives, but a little narrower."

Here is the best web page on Turkey's Fairy Chimneys you will ever see.
