The wall seems to form the eastern side of the original doorway to room I-13. It is likely original because it has sharp edges and is the same construction type as the other walls surrounding room I-13. Based on the technique of construction of the room, it was likely built during the Imperial period. The room construction was not altered like other rooms in this complex (although some cuts, undocumented in the 2017 season, were identified, which point to the robbery and/or reuse of the area). The doorway to room I-13 was not plugged, unlike many of the other doorways in the complex in the western sector of Area I 2017. This suggests the room continued to be used in later periods. Even though this wall does not have any plaster on it, the other surrounding walls making up room I-13 all have plaster on them. This is significant because none of the other walls in the western area of the complex in area I still have plaster.
