The foundations of the Constantine Bridge, one of the most impressive structures of the Roman Empire, have been discovered in the Danube near the village of Gigen in northern Bulgaria. The discovery was made due to the drastically reduced water levels of the river, linked to the current record heatwave.

According to the Regional Historical Museum of Pleven, the remains date back to 328 AD, making this bridge one of the most significant ever constructed by the Romans. The drought has allowed these ancient structures, which had been submerged for centuries, to emerge.

This is the first time the remains of the foundations have been identified, marking an important find for the archaeological history of the region and the Roman Empire in general.
