Schloss Glücksburg’s builder

Schloss Glücksburg was erected between 1583 and 1587. The builder, Duke Johann the Younger, was a son of the Danish King Christian III. He is the progenitor of the various branches of the Sonderburg House of Princes, including those of Augustenburg, Glücksburg, Plön, and Beck. Thanks to his 23 children he became father-in-law of several German sovereigns. And he was esteemed highly by the German Emperor. Duke Johann the Younger of Schleswig-Holstein-Sonderburg, although a son of the Danish King Christian III, had no part in matters of state. Instead he dedicated himself to his farming operations on his territory.
