Cross-wall

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 cross-wall dividing the inner bailey of Carmarthen 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.
