Danube River reveals ancient Roman and Byzantine ruins

Low water levels in the Danube River have revealed significant historical remains across the region. In Romania, the foundations of a nearly 1,700-year-old bridge built by Constantine the Great have become visible in Corabia. Experts note that while these structures were previously only detectable via sonar or diving, the receding waters now allow for direct observation of the stone foundations and pier bases.

Archaeologists explain that the Roman builders utilized advanced techniques, including diverting the river's flow, using formwork, and employing hydraulic pumps alongside specialized Roman cement that hardens upon contact with water.

Additionally, the receding river has exposed the ruins of a 10th-century Byzantine port city on Pakujul lui Soare island, located between the Constanta and Calarasi counties. Other visible artifacts in the region include remnants of a Nazi fleet in Prahovo.
