Ancient secrets unearthed in vast Turkish cave city

MIDYAT, Turkey — Through a basement door in southeastern Turkey lies a sprawling underground city — perhaps the country's largest — which one historian believes dates back to the ninth century before Jesus Christ.

Archaeologists stumbled upon the city-under-a-city "almost by chance" after an excavation of house cellars in Midyat, near the Syrian border, led to the discovery of a vast labyrinth of caves in 2020.
