Stirling Castle, Scotland. Built right on top an extinct volcano, a castle has stood there since roman times. as a wedding present from King James V of Scotland to his wife, drastic remodeling was done. Sadly, she died shortly after the wedding, but he marched on and handed it to his next, more famous wife, Mary of Guise, the mother of Mary, Queen of Scots.
This would be the castle of the Queen of Hearts. I chose this picture because the castle is very elaborate and has many hearts incorporated into the architecture. Also, it has a very dark and gloomy look, portraying the evil nature of the Red Queen.
