If my memory serves me right and it usually dosen't ... Castle Frankenstien was an allready abandoned building near where Mary Shelly's familly went on holiday's when she was young, and it was the castle that was the main influence for the story .
It was also very similar to an old story(I can't remember dates or names but the story was true enough) .
Quite a long time ago, (somewhere in Europe) when medicine was still a fairly new science a man who thought of himself as a Doctor decided it would be a good idea to dig up the bodies of the recently deceased to help him study the anatomy of the human body . Oddly enough when his necrophillius ( I think I made that word up ) activities were discovered the townspeople did not show the scientific awe he no doubt thought was deserved and I believe he was killed by an angry mob in the end .
I say again though my memory hasn't been the same since I had my two boys ....
