Fuerstenstein ("Prince's Stone"), Roman ionic column fragment with its base-side up in which the coat of arms of the province of Carinthia was cut in the Middle Ages. Served as a throne on the occasion of the Ducal Coronation. The Fuerstenstein, the oldest extant symbol of a sovereign existing on Austrian soil, stood near the parish church of Karnburg at the foot of Ulrichsberg mountain and is now in the Great Hall of the Provincial Parlament in Klagenfurt.
