I just ran across this link while looking something up and thought it an interesting little tidbit about the grail, the fisher king legends, and the ruins of a 13th century castle in Wales:
The Legends of King Arthur and the Castle of Dinas Bran
There are some fabulous pictures of the castle ruins here:

There’s not a whole heck of a lot of it left, to tell by the pictures, but don’t you think that castle would make a cool setting for a classic Gothicy-flavored story? 🙂 (Maybe set in the 13th century, but wouldn’t it be even spookier to have a tourist caught up in some… oh, I don’t know, time travel zap, or a hole in the space-time continuum there? They’re neat pictures, if nothing else.
