The House of Schleswig-Holstein-Sonderburg-Glücksburg, better known as the House of Glücksburg, is a collateral branch of the German House of Oldenburg. Its members have reigned at various times in Denmark, Norway, Sweden, Iceland, Greece, and several northern German states.
The water-castle Glücksburg Castle—ancestral seat of the House of Glücksburg—is located in the "Schlossteich" (palace pond) in Glücksburg (Ostsee), a town located on the Anglia Peninsula in the (Southern) Schleswigian part of Schleswig-Holstein, in the very north of Germany, where the close-by Flensburg Firth (visible in the background) constitutes the border with Denmark.
