It consists of the city Bopfingen itself and its suburbs Aufhausen, Baldern, Flochberg, Kerkingen, Oberdorf, Schloßberg, Trochtelfingen, and Unterriffingen.
A similar arrangement of two or three castles clustered closely together may be found in several places in the south part of neighbouring Alsatian Vosges: the Dreistein at Odilienberg near Obernai, the three castles on the Schlossberg near Reinhardsmunster, the Drei Exen near Eguisheim and the castle group of Haut-Kœnigsbourg/Oedenburg.
In his last will & testament of 1609 Ruprecht von Eggenberg had stipulated that he should be buried in the mausoleum on the Schlossberg to Ehrenhausen in Styria.
