A lost city of Alexander the Great, buried under the soil of Mesopotamia for centuries, is being rediscovered. Archaeologists have confirmed the location of an ancient metropolis known as Alexandria on the Tigris, situated in southern Iraq near the Persian Gulf, which was once one of the most significant trading centers in the world, hidden for over 1,500 years. Established in the 4th century BC as a port city, it connected trade routes from India to Mesopotamia and the Mediterranean world. After the 3rd century AD, it fell into obscurity when the course of the Tigris River changed.

In recent years, researchers have mapped the city's fortifications, road networks, and building blocks using drone imagery and high-resolution geophysical surveys. Archaeologists have been working in the area since the 2010s, during a time when ISIS controlled parts of Iraq. However, the full extent of the lost metropolis has only now been revealed, highlighting a significant leap in our understanding of the region's ancient history and its importance during Alexander's time.
