Burg Mauterndorf is probably built on the site of an old Roman fort that dates to 326 AD or earlier. It protected the Roman mountain road from Teurnia via Radstädter Tauern Pass to Iuvavum (present-day Salzburg) and served as a residence for the Roman administrator in the Noricum province. The original fort was destroyed during the Migration Period.
A castle built on the site in later years was funded and supported by a toll collection system for the nearby road. Evidence for this comes from a deed gift issued by Emperor Henry II in the year 1002. The castle itself was not mentioned until in 1253, th the time when the keep (Bergfried) was erected. Held by the Prince-Archbishops of Salzburg, the fortress was significantly enlarged under the rule of the archbishops Burkhard Weisbriach and Leonhard von Keutschach during the 15th century, to reach the form it still has today. The toll system on the Radtsädter Tauern Pass road supported the castle and village until in 1803 when the toll collection was abandoned during the Napoleonic Wars. In 1806 the castle became a possession of the Austrian state.
In 1894 Burg Mauterndorf was purchased by Hermann Epenstein (1851–1934), a Christian of Jewish descent, who served as an Prussian Army surgeon in Berlin. He refurbished and restored the decayed castle with great effort for use as a residence. In 1908 he obtained the minor title of a Ritter von Mauternburg by the Austrian emperor Franz Joseph I for his meritorious services and donation to the Crown.
During his service in German South-West Africa in the late 1880s, Epenstein had become friends with Commissioner Heinrich Ernst Göring. Back in Germany, he offered the Göring family hospitality in his residences. He became the attending physician (and slightly hidden lover) of Göring's wife Franziska as well as the godfather and mentor of his children. The Göring family, among them the younger sons Hermann and Albert, frequently stayed at Mauterndorf Castle as Epenstein's guests. Epenstein later became a naturalized Austrian citizen and retired after World War I to live in Mauterndorf. In 1923 he received Hermann Göring who had fled from Germany after the failed Beer Hall Putsch to evade criminal prosecution.
When Epenstein died in 1934, the property would pass to his widow who herself bequested the castle to Epenstein's sponsored child Hermann Göring on her death in 1939. Göring, however, never was formally the owner of the castle as an entry in the land register never occurred, which was decided in a yearlong lawsuit between Epenstein's heirs and the state of Germany. At the end of World War II, Göring tried to flee to 'the castle of my youth', he did however surrender to US Army forces at nearby Bruck because he was afraid of Red Army troops proceeding up the Mur valley towards Mauterndorf.
Since 1968 the building is owned by the state of Salzburg, a castle museum has been established in 2003. A number of other enterprises share the premises including a noted local restaurant and catering service. Other uses have been as a meeting place for scientific conferences of international standing and as venue for various cultural events.References:
Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
The monumental staircase on which the remains of one hundred thousand fallen soldiers are lined up and which has at its base the monolith of the Duke of Aosta, who was the commanding officer of the third Brigade, and gives an image of a military grouping in the field of a Great Unity with its Commanding Officer at the front. The mortal remains of 100,187 fallen soldiers lie here, 39,857 of them identified and 60,330 unknown.
