A sprawling 3,500-year-old fortress offers tantalizing clues about a culture that once dotted the southern Caucasus mountains with similar walled communities.
Archaeologists recently used a drone to map a sprawling 3,500-year-old fortress in the Caucasus Mountains of southern Georgia. The detailed aerial map offers some tantalizing clues about the ancient culture whose people built hundreds of similar fortresses in a mountainous region that spans the modern countries of Armenia, Azerbaijan, Georgia, and Turkey. Based on their survey and excavations within the fortress walls, Cranfield University archaeologist Nathaniel Erb-Satullo and his colleagues suggest the fortified community may have been a place where nomadic herders converged during their yearly migration, but the evidence still leaves more questions than answers.

An abandoned ancient megafortress
The half-buried Bronze Age ruins of Dmanisis Gora perch on a windswept promontory a few kilometers away from a cave where Homo erectus (or a close relative) lived 1.8 million years ago. Deep, steep-sided gorges run along two sides of the promontory, and sometime between 1500 and 1000 BCE, people stacked boulders into a double layer of high, thick walls to block off the end of the plateau from the plains to the west. Sheltered between the 4-meter high, 2.5-meter wide walls and the 60-meter-deep gorges, people built dugout houses, then later aboveground stone ones, along with stone animal pens and other buildings.
