Spy satellites and drones have helped scientists find what many are saying is the lost city of Alexander the Great. After 2000 years, archaeologists have discovered the ancient city in northern Iraq using satellite imagery.

Experts at the Iraq Emergency Heritage Management Training Scheme (which was set up in 2015 to combat the destruction of ancient heritage by the Islamic State) have been working at the Qalatga Darband site, which is 6.2 miles southeast of Rania in Iraqi Kurdistan. ISIS launched a series of wanton attacks on sites of historic and religious importance across a swathe of Iraq and Syria. Last year, for example, ISIS released a video that showed militants using sledgehammers and drills to destroy artifacts in Iraq’s Mosul Museum. In 2015, ISIS took control of the ancient city of Palmyra in Syria and subsequently demolished some of its best-known monuments, such as the Temple of Ba’al. The jihadists, who beheaded the city’s former antiquities chief, also used Palmyra’s ancient amphitheater for public executions.

Backed by United Kingdom government funding, the project involves archaeologists from the British Museum and their Iraqi counterparts.
