The East Gate in the inner walls opens onto the King's Gate of the outer walls. The main gatehouse, consisting of two large crenellated bulwarks, and drawbridge opens onto the market square of the winter town outside, but the Hunter's Gate on the opposite side of the castle opens directly onto open fields and is favoured by hunting parties. The outer walls have guard turrets built into them. The inner walls are crenellated with more than thirty watch towers built into them. The outer walls are 80 feet tall and the inner are 100 feet tall, with a wide moat located between them. Winterfell is a large stronghold extending across many acres of territory, defended by two layers of strong stone granite walls.
