After twelve centuries of silence beneath the sand, the lost city of Alexander the Great has resurfaced in southern Iraq, in what researchers are calling one of the most significant archaeological discoveries in the country’s history.
The site, long thought lost, has been identified near Jebel Khayyaber through a combination of remote sensing technology, drone imagery, and non-invasive geophysical surveys.
An international team of archaeologists, led by Professor Stefan Hauser of the University of Konstanz (Germany), has brought this ancient port city back to light. Founded in 324 B.C. on the banks of the Tigris River, the city was originally known as Alexandria on the Tigris and later renamed Charax Spasinou. It was one of the last cities founded by Alexander before his death in 323 B.C.
Access was blocked for decades by political instability and conflict — most notably the Iran-Iraq War, which placed part of the site inside a military zone. Fortunately, the city survived even modern conflicts and can now be studied.
Technology Breaks the Desert’s Silence
Rediscovering this settlement took not shovels, but cutting-edge sensors. The rediscovery was made possible by a clue that had been overlooked since the 1960s, when British researcher John Hansman noticed unusual rectilinear shapes in Royal Air Force aerial photographs.
Long before that, Pliny the Elder, the Roman author and naturalist, had accurately described the city’s location as sitting atop an artificial elevation between the Tigris and the Eulaeus River (Karun). Although the site had been a subject of speculation since the 1960s, the area remained off-limits until 2014, when Hauser’s team conducted more than 310 miles of surveys on foot.
While they gathered thousands of pottery and brick fragments, it was the use of drone photogrammetry, satellite imagery, and high-resolution magnetometry that ultimately revealed the city’s hidden layout. With minimal digging, the technology allowed researchers to virtually reconstruct a city of striking geometric precision.
The layout showed streets arranged in a grid, massive residential blocks known as insulae, and monumental temples. The survey also identified irrigation canals, an inland harbor lake, and even a palace surrounded by gardens. Experts say the city’s scale and design rival those of Alexandria in Egypt.
A Port Between Two Rivers
Like the other cities Alexander founded, Charax Spasinou was conceived as a cosmopolitan hub — a meeting point for diverse peoples and trade.
From around 300 B.C. to A.D. 300, Charax served as the main commercial link between East and West. Strategically positioned, the city served as the gateway through which exotic goods flowed across Mesopotamia to supply the imperial capitals of Seleucia and Ctesiphon.
Through its streets passed spices, precious metals, ivory, rare woods such as rosewood, semi-precious stones, and — most likely — silk from China. With an estimated population of hundreds of thousands, the city was a hub of the ancient world’s commerce, driven by trade in luxury goods and textiles.
However, its history was also defined by the persistent forces of nature. Shortly after its founding in 324 B.C., the city was destroyed by river floods. It was later restored by King Antiochus V and ultimately by King Hyspaosines, who built massive defensive walls stretching nearly 6 miles around the city.
Over the centuries, nature took its toll. As river sediment accumulated, the shoreline gradually retreated southward, and the Tigris River shifted its course. As the water receded, the port fell out of use, and the city slowly faded from history.
And yet, a city built to stand at the center of ancient trade lay quietly buried beneath dust and farmland. Researchers hope that future excavations will uncover one of the last great chapters of Alexander the Great’s legacy.
