Khaybar forts were a series of strongholds built in Khaibar. In 629 CE the Khaybar oasis was divided into three regions: al-Natat, al-Shikk, and al-Katiba, probably separated by natural divisions, such as the desert, lava drifts, and swamps. Each of these regions contained several fortresses or redoubts including homes, storehouses and stables.
