Dorostorum

Dorostorum is an ancient fortified settlement and frontier town positioned on the lower Danube. In Roman times its name appears in sources as Dorostorum or Durostorum, and it is commonly identified with ruins near the modern Bulgarian town of Silistra. The site lies along the Danube limes, reflecting its role as a strategic garrison and administrative center on the northern frontier of the Roman province system.

Historically, Dorostorum developed from a military installation into a civilian settlement that supported trade and localization along the Danube. It served as a key link in the network of Roman frontier towns, contributing to the defense and administration of Moesia Inferior (and later Moesia Superior). In Late Antiquity the fortress continued to function on the frontier and is attested in later Roman and early Byzantine contexts as a fortified site in the region.

In the medieval period the site became known as Dorostol and remained a significant fortress on the Danube frontier in subsequent Byzantine and Bulgarian border conflicts. It appears in medieval chronicles and cartographic references as a strategically located stronghold controlling movement along the Danube corridor. The fortress’s enduring position underscores the long-term military and political importance of the Danube boundary in southeastern Europe.

Today, Dorostorum is of archaeological and historical interest. Excavations and surveys have uncovered remnants of stone walls, fortifications, and associated artifacts that shed light on Roman and post-Roman occupation. The modern city closest to the site is Silistra, Bulgaria, and the Dorostol-Dorostorum remains are a noted point of reference for studies of Danube-frontier networks in antiquity and the Middle Ages.
