Low water levels on the Danube River in Bulgaria, caused by extreme summer heatwaves and drought conditions, have revealed the foundations of the ancient Constantine Bridge, built during the reign of Emperor Constantine I in AD 328. This rare exposure provides Bulgarian archaeologists with a unique opportunity to study and document one of the Roman Empire's significant engineering feats. The bridge, which connected the ancient cities of Ulpia Oescus and Sucidava, is considered one of the longest ancient bridges but was likely destroyed around AD 367.
