Counts · Duchy of Carinthia · as at first light, 1 January 1200

Ortenburg

The Ortenburg counts hold the middle Drava valley of Upper Carinthia: when the counts of Lurn died out in 1135, Gorizia took the land west of Möllbrücke, Salzburg took Pusarnitz, Sachsenburg, Gmünd and Stall, and the Ortenburgs took the ground east of Möllbrücke down to Rennstein near Villach.

Their castle stands south of the Drava west of Spittal, first named in 1093. In 1191 Count Otto II and his brother Hermann the archdeacon founded a hospital for travellers over the Katschberg and the Radstadt Tauern on the Lieser, confirmed by Archbishop Adalbert on 11 April 1191: the beginning of Spittal. Otto II probably died on the crusade of 1197, and the house on 1 January 1200 is in the hands of his young heirs and his widow Brigitta of Heunburg.
