Burg Sommeregg

Geschichte

Sommeregg is a medieval castle near Seeboden in the Austrian state of Carinthia, Austria. It is situated in the foothills of the Nock Mountains at an altitude of 749 m. The fortress served as an administrative seat in the Upper Carinthian estates held by the Counts of Ortenburg and Celje; it later was the residence of the Graben and Khevenhüller dynasties; ministeriales of the Austrian House of Habsburg.HistoryThe castle was probably erected in the 12th century, as one Witemarus de Sumereke was already mentioned in an 1187 deed issued at Neustift Abbey in Tyrol. The Lords of Sommeregg then served as ministeriales of Count Otto II of Ortenburg, who ruled over extended estates in Upper Carinthia, rivalling with the House of Gorizia and the Salzburg archbishops. On 29 May 1275 the marriage of Otto's granddaughter, Euphemia of Ortenburg-Hardegg, with Count Albert I of Gorizia was arranged here.
