Once a significant caravan stop on the spice and incense route across the southern Arabian plateau, British explorer Freya Stark dubbed the mud city “the Manhattan of the desert” in the 1930s. Every aspect of Shibam’s design is strategic. Perched upon on a rocky spur and surrounded by a giant flood wadi, its elevated position shields it from flooding while maintaining proximity to its primary source of water and agriculture. The city was built on a rectangular grid behind a fortified wall—a defensive arrangement that protected its inhabitants from rival tribes and offered a high vantage point from which enemies would be seen approaching.
