Doune Castle
Scotland

A Baronial masterpiece; belongs to the period of the feudal barons before the age of the lairds with their tower-houses; has TWO great halls (one for the nobility, one for the retainers); a must-see. Given that there was both a retainers' hall and a baronial hall, the kitchen area was provided with several huge fireplaces (big enough to roast an ox in). The castle defenses apart from very thick walls are not that impressive, but still, outward-facing windows are very rare and there are plenty of gun loops.
