(7-00) North view of the Gorge Wall and Drawbridge. 2000 Tour Guide: Gorge Wall: This, the rear section of the fort, contains the sally port, or fort entrance. Officers lived in most of the rooms here. Today, several are furnished to represent various aspects of life at the fort. 2000 Tour Guide: The Drawbridge: A part of the fort's overall defense, the drawbridge is constructed in such a way as to make forced entry difficult. As it is raised, a strong wooden grille, called the portcullis, drops through  the granite lintel overhead: bolt-studded doors are closed behind that. An inclined granite walk leads between two rows of rifle slits, past another set of doors, and into the fort

When filled from this ditch, the moat formed an effective barrier to hinder the approach of infantry
