Schloss Drachenburg in Königswinter, a town near Bonn, Germany. I can't find the proper words to describe the awesomeness of this castle and of this photograph! It's like it jumped straight out of the pages of my childhood fairy tales!
Church of Our Saviour on the Spilled Blood, St Petersburg, Russia. As a ghost, I am looking for a castle to haunt. What about this one? I know it isn't technically a 'castle' but look at its magnificent size! I think it would still be splendid to haunt.
