General description
                        Double-coursed, extramural wall.
                     
                    
                        Use history
                        Unknown use--possibly associated with the reservoir adjacent to the west; appears to be too roughly built to be a room wall.
                     
                    
                    
                        Excavation procedure
                        Not excavated, exposed only.
                     
                    
                        Portion excavated
                        Only the portion within the excavation unit; feature continues outside the unit to north and south.
                     
                    
                        Horizontal location
                        Feature occupies the east half of the excavation unit; wall is 46 m northeast of the great tower.
                     
                    
                        Vertical location
                        Extramural surface above bedrock.
                     
                    
                        Construction
                        Wall is double-stone-wide, semi-coursed masonry that rests on an orange-brown silty fill surface just above bedrock. Stones are large and blocky, mortar is gray.

                        Degree of preservation
                        Some of the wall has fallen and a portion of the remaining uppermost courses are beginning to tilt due to exposure to the elements.
