Archaeologists have documented a flooded medieval settlement at Toru-Aygyr beneath the northwestern waters of Lake Issyk-Kul in Kyrgyzstan. Its historic name, population and the reason it went underwater remain unknown. Finds including buildings, ceramics and a large Muslim cemetery point to a settlement connected with a Silk Road route through the region—not yet to a city whose identity or trading history has been established.
What is the sunken Silk Road city in Kyrgyzstan?
The site is the Toru-Aygyr flooded complex in Lake Issyk-Kul. Researchers have described it cautiously: expedition leader Valery Kolchenko, a researcher at the Institute of History, Archaeology, and Ethnology of the National Academy of Sciences of the Kyrgyz Republic, said, “The monument under study is a city or a large commercial agglomeration on one of the important sections of the Silk Road.”

That description reflects the evidence without assigning the settlement a historical name that researchers have not established. AFP’s 5 October 2026 report says the city’s name and population are unknown. The researchers associate the site with a Silk Road route through the Issyk-Kul area, historically within the sphere of Karakhanid control. That regional context makes the remains relevant to medieval settlement, trade and religious history, but it does not establish what goods this particular community traded.
What have archaeologists found underwater?
In its report on the 2025 autumn expedition, the Russian Geographical Society says teams explored four underwater areas at depths of 1–4 m. The project began in 2024, according to AFP’s 2026 account, and brings together Russian and Kyrgyz archaeological institutions.
#1 Best Overall
- Remains of buildings made with baked brick, as well as stone structures.
- Wooden structural remains and a stone millstone.
- Medieval ceramics, which may help refine dating and identify production methods.
- A decorated public building whose function is unresolved: researchers have proposed a mosque, bathhouse or madrasa.
- Burials across a cemetery area reported by AFP as about 300 by 200 m. That measurement describes the reported cemetery extent, not the total area of the settlement.
The Russian Geographical Society dates the Muslim necropolis to the 13th–14th centuries and reports that burials were oriented toward the Qibla. It also describes three nearby burials considered possibly older and non-Islamic, but does not give their precise dates. This suggests a more complex history of use than the cemetery date alone can explain.
Expedition head Maksim Menshikov of the Institute of Archaeology of the Russian Academy of Sciences said, “People here practiced various religions: pagan Tengrianism, Buddhism, Nestorian Christianity.” The statement offers a regional interpretation; it does not identify the religion of every person buried at the site.

What can the evidence say about the settlement’s size and age?
AFP reports researchers’ tentative estimate that the settlement may have covered up to 5 square kilometres. This is an upper estimate, not a surveyed or confirmed city boundary. Nor does the 13th–14th-century date reported for the Muslim necropolis establish when the whole settlement was founded or when it ended.

The Russian Geographical Society says timber samples were sent for dendrochronological analysis and accelerator mass spectrometry dating. The team also used underwater drilling and sampled mud walls and buried soils to investigate how the settlement developed. AFP notes that pottery may help refine dates and identify production methods. The cited reports do not publish results from these analyses, so they do not yet settle the site’s full chronology.
Why is the settlement underwater?
There is no confirmed explanation for when or how the settlement was submerged. The accounts describe competing possibilities, not a demonstrated cause:
- Earthquake-related change: The expedition account includes an earthquake hypothesis. Geologist Andrei Strelnikov of the Russian Academy of Sciences told AFP that a “past seismic disaster” was the probable cause.
- Landslide or natural damming: AFP reports a possible landslide or gradual flooding after a tectonic dam formed. These are proposed mechanisms, not confirmed observations of what happened at Toru-Aygyr.
Dating the settlement and its buried layers, alongside geological investigation of the area, may help distinguish between explanations. For now, neither the timing of submergence nor its mechanism is established.

The remains offer a rare underwater view of settlement in the Issyk-Kul region, along a route associated with Silk Road movement. Buildings, ceramics and burial evidence can help researchers investigate how communities lived and how religious traditions changed over time. The evidence is still being analyzed, so the site’s historical name, exact scale and place in any specific trade network remain open questions.
Expedition director Maxim Menshikov, as quoted by AFP, called the site “a blind spot in history, even though it is right in the center of Central Asia.” Its significance lies in the potential to fill gaps in the regional record—not in a settled identification of a famous lost city.
