I would never want to live in medieval Europe. No indoor plumbing and no central heating made for a dirty, smelly, drafty and infested existence. However, medieval castles are pretty darn cool. Visited Trim Castle in Ireland, the site where Braveheart was filmed. Got my fill of arrow slits and murder holes and learned random facts like most tower staircases run clockwise (to give the advantage to right-handed defenders) and that the worst job in history is the gongfarmer.
