Nivelul scăzut al Dunării scoate la iveală unul dintre cele mai lungi poduri ale Antichității, între Bulgaria și România

The low water level of the Danube has revealed parts of the foundations of the Bridge of Constantine the Great, allowing Bulgarian archaeologists to study this Roman engineering marvel. Built under Emperor Constantine and inaugurated in 328, the bridge connected ancient Ulpia Oescus in Bulgaria to Sucidava in Romania. Archaeologists view this as a rare opportunity to document and study the structure, which is mostly submerged. The bridge, approximately 2,400 meters long, was used for a short time and largely destroyed around 367. Researchers have recently documented the visible remains near Ghighen, Bulgaria, using drones for assessment.
