Baba Vida Fortress and Konaka Museum

Baba Vida is a medieval castle on the bank of the Danube in Vidin and the town's main landmark. It has two rings of walls and about nine towers, three of them to their full height with the original battlements, and is the only entirely preserved medieval castle in the country. Building began in the 10th century on the site of the Roman fort of Bononia.

The Konaka museum, part of the Vidin History Museum, is in an 18th-century Ottoman building that later served as a police station; its central tower was once a lighthouse.
