Drastar, Medieval fortress in Silistra, Bulgaria.

Drastar is a medieval fortress situated along the southern bank of the Danube River with substantial stone walls and defensive towers built during multiple periods. The ruins cover a significant area where structures from ancient Roman times and the Bulgarian medieval era stand side by side.

Drastar is a medieval fortress built on the foundations of the ancient Roman city of Durostorum, on the site of present-day Silistra. In the 9th century it was the centre of a comitatus, an administrative district. After the Christianisation of the Bulgarians it became the seat of the Bulgarian Orthodox Church, and during the Second Bulgarian Empire it was a metropolitan centre. Excavations have uncovered remains of the fortress, coins and weapons.

The name Drastar comes from the Old Bulgarian word дръстръ, used for the medieval fortress on the site of today's Silistra. After the Christianisation of the Bulgarians the town became the seat of the Bulgarian Orthodox Church, and in the Second Bulgarian Empire it was a metropolitan centre. Excavations have yielded coins, weapons and other finds.

The fortress site lies in Silistra, on the ground of the medieval Drastar founded over ancient Durostorum. Excavations there have yielded remains of the fortress walls, coins and weapons. The terrain is uneven, so allow time to walk the different sections and wear sturdy shoes.

Archaeological digs at the site have yielded coins, weapons and other finds, evidence of the medieval fortress that rose on the foundations of the Roman city of Durostorum. The Bulgarian name Дръстър, from Old Bulgarian дръстръ, survives in the modern town of Silistra.
