Inspiration!

As my husband sat down for our quiet time after dinner he looked over at me and said, "I sent you some inspiration today."
I almost scratched my head in confusion. I had no idea what he was referring to.
He looked hopefully at me and clarified, "You know how you are inspired by music and pictures... for your books. I sent you a castle."
My heart cracked a little and I fell even more in love with him at that moment. I have no idea where to use this castle, but... now I must.
Any suggestions?
