 The crown or hat is described as "a grey Slovenian Hat with a grey cord and four leaves suspended from the brim".In 1358 the Habsburg Duke Rudolf IV imparted coats of arms to those provinces without them and ordered the "Slovenian Hat" to be placed above the arms of the Slovenian March (later called Lower Carniola and now a province of Slovenia).A crown called the "ducal hat" of Carniola still exists in Graz.
