The Prince's stone, where Karantanian dukes were installed, is encircled by the twelve stars of Europe alternated with the letters of the word "SLOVENIJA" (Slovenia).

The Prince's Stone is the reversed base of an ancient Ionic column that played an important role in the ceremony surrounding the installation of the princes of Carantania in the Early Middle Ages. After the incorporation into the Frankish Empire the procedure held in Slovene was continued as the first part of the coronation of the Dukes of Carinthia, followed by a mass at Maria Saal cathedral and the installation at the Duke's chair, where he swore an oath in German and received the homage of the estates.
