Archaeologists have established that the subterranean network beneath an underground city in Türkiye covers a far wider area than previously understood. The discovery adds to the significance of a site already regarded as among the world’s largest and most sophisticated underground urban environments.
The revised assessment shifts attention from individual chambers and passageways to the scale of the connected system. Its extent suggests a more complex built environment than earlier mapping had captured, with implications for how researchers interpret the city’s planning and use.
Underground architecture poses distinct challenges for documentation, conservation and public access. As the known footprint grows, so does the need to understand how the network is arranged and how its spaces relate to one another beneath the surface.
For architects and urban historians, the findings offer another reminder that major built landscapes can remain only partially visible even after centuries of study. The expanded archaeological picture was reported by Architectural Digest.
