Archducal hat

The archducal hat (German: Erzherzogshut) is the insignia of the Archduchy of Austria and is kept in the treasury of Klosterneuburg Monastery.

The final crown of the Archduchy of Austria was made in 1616 for the regent of the Tyrol, Maximilian III.

It was brought to Vienna in 1620 for the Ceremony of Homage by the Estates (the so-called Erbhuldigung) for the new ruler, and was last there in 1835.

Margaret of Austria, aunt of Emperor Charles V and Regent of the Netherlands, is also shown wearing one on her tomb by Conrad Meit and in some images.

The coat of arms of the federal state of Upper Austria features the archducal hat on the top.
