This east-west concrete wall seems to function as a party wall between rooms H-11 and H-12. The western limit of this wall seems to be the eastern limit of a possible doorway between rooms H-11 and H-12. The northern limit of this wall in room H-11 seems to be abutting a drainage feature, which possibly connects to the drain in room H-10, but need to be studied and confirmed in future seasons.
