To the southeast of the Dar al-Makhzen palace enclosure was a large complex which served a mainly utilitarian and consisted of three major elements. The first part was an enormous structure known as the "House of the Ten Norias"[1][2] or the Dar al-Ma ("House of Water").[41] It consisted of a large central chamber surrounded by smaller rooms around which, in turn, was a large vaulted corridor which gave access to 15 domed chambers. These domed chambers each held a noria or mechanical hydraulic system which drew water from a deep well reaching down to the phreatic table, via a series of pails or buckets chained together and raised by a horse-drawn wheel.
