Izkī
Izki was an inland Omani oasis whose old settlement comprised the neighbouring walled towns of al-Nizar and al-Yemen. Their closely placed but distinct enclosures formed a paired urban landscape, with a Yaʿruba fort between them. Al-Yemen underwent destruction and rebuilding during the eighteenth century, leaving a more regular street pattern within the old settlement.
Water ownership was another enduring part of the oasis's organisation. A manuscript register of the Falaj al-Malki, begun about 1825, records the names and holdings of owners of irrigation-water shares, showing how a resource shared through the irrigation channel was allocated. Town walls, reconstruction and the documentation of water rights together reveal an oasis shaped by the defence of settled space and the administration of its water supply.
