In brief
Recent excavations in eastern Uzbekistan have revealed the remains of two medieval cities, Tugunbulak and Tashbulak, demonstrating that high-altitude settlements were significant nodes in the historic Silk Road trade network. Using advanced lidar technology, researchers uncovered a wealth of artifacts and infrastructures, prompting a reevaluation of historical urbanization in Central Asia.
Archaeologists have made a groundbreaking discovery in the grassy mountains of eastern Uzbekistan, unveiling the remnants of two medieval cities that could drastically alter our understanding of the Silk Road. Traditionally viewed as a network primarily connecting lowland cities, this research highlights previously overlooked highland settlements that played a crucial role in the exchange of culture and goods between the East and West.The larger city, Tugunbulak, which sprawls across at least 120 hectares, is situated over 2,000 meters (6,600 feet) above sea level—an astonishing altitude for a sizeable urban center. This historic find, led by Farhod Maksudov of Uzbekistan's National Center of Archaeology and Michael Frachetti from Washington University in St. Louis, was enabled by innovations in remote sensing technology, specifically lidar (Light Detection and Ranging), which allowed for detailed environmental mapping from above.Historical evidence suggests that Tugunbulak and its smaller counterpart, Tashbulak, thrived between the 8th and 11th centuries, a time when the region was under the influence of a formidable Turkic dynasty. The challenges of inhabiting such high altitudes are significant—only about 3% of the global population resides above 2,000 meters today.The discovery of Tashbulak was serendipitous, occurring during a trek in 2011 where the team encountered burial sites and pottery shards. However, it wasn't until 2015 that they were alerted to Tugunbulak's presence by a local forestry official, leading them to a surprising find: the official's home was constructed atop a medieval citadel.The academic community was initially skeptical about the significance of the findings. Mr. Frachetti expressed that they faced challenges in scientifically documenting the site to validate its importance. Nevertheless, upon their return in 2022 with a drone equipped with lidar, they unveiled numerous architectural features of Tugunbulak, including walls, towers, and complex fortifications.Researchers propose that the settlement of these communities may have been influenced by the region's rich iron ore deposits, as strong winds could be harnessed to fuel iron smelting processes. However, this economic advantage potentially led to environmental degradation. The historical juniper forests that once dominated the landscape were likely cleared to support iron production, resulting in increased flash floods and avalanches and eventual instability for the communities.Experts regard this discovery as pivotal, with Peter Frankopan from Oxford University highlighting the remarkable interconnections that the findings illustrate in ancient trade and resource exploitation. Zachary Silvia from Brown University notes that high-altitude urban sites are extremely rare in archaeology, making this research a vital contribution to our understanding of medieval urban life in Central Asia.As the academic community continues to digest this unveiling of highland cities, the implications for historical trade, cultural exchanges, and environmental impacts remain profound and far-reaching.
