Doboka
Doboka (Dăbâca, Dobeschdorf) is in Transylvania which is in Romania. The village is famous for its ruined castle which used to be the favorite place of Queen Isabella, the widow of Hungarian King János Szapolyai in the 16th century. The village is 41 km north of Kolozsvár (Cluj, Klausenburg) and used to be the center of Doboka County.
Doboka’s name derived from the Hungarian Chief Doboka who was the father of Csanád, the cousin of King Saint Stephan (István). The castle was first mentioned in 1214. Its earth castle was built when the Christian Hungarian state was established but it was reinforced with 3-5 meters high stone walls in the 14-15th century.
Doboka castle was the place from where King Salamon, Prince László, and Prince Géza set out against the intruding Pecheneg (besenyő) tribes in 1068 to beat them at the Battle of Cserhalom. It was the battle where László freed the Hungarian girl after his duel with the Pecheneg warrior. (See picture.)
The castle belonged to the king but it was one of the seven castles which were gifted to the Bishopry of Transylvania in 1099. Doboka Castle supervised the next villages: Cege, Bádok, Kide, and Csomafája. Queen Isabella, the mother of the first prince who established the Transylvanian Principality, used to dwell in the castle. Allegedly she was minting coins in the castle. The last commander of the castle was Bádoki Mátyás at this time.
The castle may have been destroyed in the time of General Giorgio Basta who devastated Transylvania between 1598-1604. Its church was built in the 13th century. I found only one video about the castle and it is in the Hungarian language.
