A rare and valuable ring has been found during the National History Museum's (NIM) regular archaeological excavations at the Kokalyanski Urvich Fortress' citadel.

Bulgarian archaeologists recently discovered an 11th century fragment of a distillation vessel used for the production of the country's traditional fruit brandy, which is known as rakia.

The fragment was uncovered during the excavation works, which are being conducted by the National Historical Museum (NIM) at the medieval Lyutitsa fortress.
