In the northeast of a country like Bulgaria, right within the modern city of Silistra, lie impressive ruins known as the Ancient City of Durostorum–Drastar. This national archaeological reserve is a unique multi-layered monument where an ancient Roman military camp meets a medieval Bulgarian capital. Founded as early as the 2nd century AD as a key outpost of the Roman Empire on the Danube, the city remained an important center for defense, religion, and culture for centuries.

Today, visitors can see evidence of the former greatness of Durostorum: fragments of powerful fortress walls, remains of Roman baths, and pagan temples. During the era of Emperors Diocletian and Constantine the Great, this fortress was considered one of the most impregnable on the border with the barbarian world. The site is particularly significant because the ancient foundations served as the basis for the medieval city of Drastar, which became the spiritual center of the First Bulgarian Empire.
The reserve covers a significant part of central modern Silistra, turning a walk through the city into a true journey through time. Here, one of the oldest churches in Bulgaria from the 9th century, monumental khan residences, and Byzantine fortifications stand side by side. Durostorum–Drastar is not just an open-air museum, but a place where legends of Roman legionnaires and great Bulgarian rulers come to life.
