"However, if I am reading this site correctly the building of this castle was not started until 1435 and not completed until 1589, so its really one of those rare examples of a building designed and built on the fringes of a major technological revolution where tradition still held sway over common sense, and it only held out for eleven weeks under seige." If my living room/bedroom held out 20min under seige I would be shocked. Ok I did forget the cannon ports but think this was a tower that expected a relief force soon. Not a castle expecting to stand alone. SadCat
