A massive Bronze-Age "mega fortress" has been uncovered in the Caucasus mountains, intriguing researchers who are trying to determine the role of this monumental prehistoric site at the junction of Europe and Asia. Dubbed Dmanisis Gora, this expansive fortified settlement overshadows all surrounding fortifications, but offers scant evidence regarding its inhabitants.
Dated to around 3,000 years ago, Dmanisis Gora is one of many fortress settlements that appeared in the South Caucasus between the second and first millennia BCE. Following initial excavations at the site in Georgia in 2018, archaeologists were surprised when they returned the following year to find the remains of a second set of fortification walls surrounding the inner fortress, thus massively expanding the size of the settlement.
Dmanisis Gora is so vast that it cannot be fully appreciated from the ground level; only drone photography can capture its true extent. In total, researchers captured 11,000 aerial images of the location, which they combined to create a comprehensive representation of the fortress.
“The results of this survey showed that the site was more than 40 times larger than originally thought, including a large outer settlement defended by a 1-kilometer-long [0.6-mile] fortification wall,” explained study author Dr Nathaniel Erb-Satullo in a statement. “These datasets enabled us to identify subtle topographic features and create accurate maps of all the fortification walls, graves, field systems, and other stone structures within the outer settlement.”
According to the researchers, the inner and outer fortification walls were “mutually dependent with respect to defence,” meaning they functioned as one system of protective barriers and neither wall could be consid
