Grafen von Cilli
The earliest reference to Celje Castle dates from 1322 and calls it “purch Cylie”. Later, the castle was known by various names, including “vest Cili” (1341), “castrum Cilie” (1451), “gsloss Obercili” (1468). It is noteworthy that the name “Obercili” - "Upper Celje" - only appears after the Counts of Celje had died out. Its original name was “grad Celje” ("Celje Castle").
