Drone reveals ancient fortress is 40x larger than archaeologists once thought

Drone photographs taken of a 3,000-year-old "mega fortress" nestled deep in the Caucasus Mountains reveal the settlement is actually 40 times larger than archaeologists once thought. New aerial images of the Dmanisis Gora settlement, located in present-day Georgia, show a large land area well guarded by steep gorges and plastered with various stone structures and field systems. Though the structure's inner fortress has been well-documented for several years, new mapping made possible thanks to a simple hobbyist drone helped redraw the Bronze Age monument's boundaries. Researchers shared their findings this week in the journal Antiquity. The Dmanisis Gora is one of several documented fortresses that popped between the Middle East and the Eurasian Steppe sometime between 1,500 and 500 BCE.
