Using a revolutionary new technology known as Quantum-Resonance Lidar, archaeologists have discovered a vast, previously invisible network of subterranean tunnels and dwellings beneath the 2,500-year-old Ziggurat of Chogha Zanbil in Iran. Unlike traditional radar, this technology can penetrate high-density clay and brick to reveal structural voids with centimeter-level precision.
The newly mapped network includes advanced water-cooling chambers and ritual spaces that suggests the Elamite site was significantly more populous and technologically complex than surface excavations indicated. Conservationists are now developing a non-invasive stabilization plan using the lidar data to reinforce these underground structures against seismic activity without disturbing the historic surface layers of the ziggurat.
