The Danube Limes, a UNESCO World Heritage site in Europe, is a section of the Roman Empire’s northern frontier along the Danube River, recognized in 2021 across Austria, Germany, and Slovakia. Spanning 493 kilometers, it includes 77 sites—fortresses, watchtowers, and settlements like Carnuntum and Regensburg—built between the 1st and 5th centuries CE to defend against Germanic tribes. This well-preserved network of military architecture and infrastructure highlights Roman engineering and urban planning, offering insight into the empire’s strategic control and cultural exchange along its volatile borderlands.
