On the northern side of the Dar al-Khalifa was a walled cantonment area.
This site has been identified as the area allotted by al-Mu'tasim to Khaqan 'Urtuj and his followers, who were said to be segregated from the general populace.
At some point, the cantonment appears to have housed the servants who worked in the caliphal palace.
A smaller palace (possibly the 'Umari palace built by Khaqan 'Urtuj) and storehouses were located here, and al-Hayr marked the eastern boundary of the area.

Immediately to the north of the cantonment of Khaqan 'Urtuj was a second, diamond-shaped area.
This cantonment is tentatively identified as al-Waziriyya, containing the Waziri palace built by Abu al-Wazir.
Like the cantonment of Khaqan 'Urtuj, it may have served as housing for the caliphal servants.
