Baba Vida (Bulgarian: Баба Вида) is a medieval castle in Vidin in northwestern Bulgaria and the town's primary landmark.

Although Gamza and Kula married to drunkard and warlike nobles, Vida remained unmarried and built the castle in her city.

[2] Baba Vida served as part of Vidin's main defensive installation during the course of the Middle Ages and acted as the citadel of the most important fortress of northwestern Bulgaria.

The crusade ended in the disastrous Battle of Nicopolis at Nikopol, Bulgaria, with the Ottomans capturing most of Sratsimir's domains shortly thereafter, in 1397.

The castle played a role during the Ottoman rule of Bulgaria, serving as a weapon warehouse and a prison, also as residence for Osman Pazvantoğlu, and it has been no longer used for defensive purposes since the end of the 18th century.
