Thank you to everyone on here who advised me about Thornbury and the area and gave me some really interesting info about the castle history! It really helped me get the most out of my trip. I've uploaded some pictures of the castle on flickr, so everyone is more than welcome to view them. Anyone who is considering a stay at Thornbury Castle feel free to view my photos and ask me any questions  We'll have to set up an Anne Boleyn Files trip advisor page on the forum
