The Lost City Alexander Built—Then the River Left

Alexander the Great founded Alexandria on the Tigris as a strategic port in southern Mesopotamia. Centuries later, the waterways that made the city rich shifted away. Today, researchers identify the vast ruins at Jebel Khayyaber in southern Iraq with Alexandria on the Tigris, later known as Charax Spasinou. Drone imagery, aerial photography, surface survey, and geophysical mapping have revealed an enormous planned city with streets, residential blocks, temples, workshops, canals, industrial zones, and harbor facilities. The city flourished as a major trade hub linking Mesopotamia with the Persian Gulf and routes stretching toward India and Central Asia. Its commercial importance declined as sediment changed the coastline and the Tigris shifted westward, though occupation may have continued for centuries afterward. 📚 Research & sources ▸ University of Konstanz — “Alexandria on the Tigris — the forgotten metropolis” https://www.campus.uni-konstanz.de/en... ▸ University of Konstanz — Archaeological Research in Spasinou Charax and its Environment https://www.geschichte.uni-konstanz.d... ▸ Archaeology Magazine (2026) — “New Research Confirms Location of Lost City Founded by Alexander the Great” https://archaeology.org/news/2026/02/...
