Plan of Conway Castle showing the cross-wall dividing the two wards
A cross-wall is an interior dividing wall of a castle. It may be an external wall dividing, for example, the inner and outer wards, or it may be a wall internal to a building such as the keep.[1]
An example of the external variety is the great cross-wall separating the inner and outer baileys of Conway Castle in Wales. At Rochester Castle in Kent, the cross-wall within the keep was used for protection when the castle was attacked in 1215.[1]
