The castle Emmerberg was probably built around the middle of the 12th century. 1170 Emmerberg is first mentioned in a document with "Durinch de Emberberch". At the time of the Babenberger the Emmerberger counted among the most important families of the country.
The Emmerberger died out in 1455, but already in 1384 Ludwig von Eckartsau was entrusted by Duke Albrecht III with the castle. After that, the owners changed quite often. Among others, the Wolfenreut (around 1430), Teufel, Brassican, Spaur (around 1500), Heussenstein (from 1706) and Vincenz von Suttner (1805) seem to be feudal owners. The destruction of the castle was initiated in 1760 by Count Heinrich von Heussenstein.
For fiscal reasons, he had the oak roof chair covered and sold. One of the following owners, Alexander Wilhelm Graf Wartensleben, used the walls in 1821 as a quarry to build a stud at the foot of the castle hill. The surrounding farmers also got building material here. Graf Wartensleben soon had to file for bankruptcy. From the mass acquired in 1833 Archduke Rainer, viceroy of Lombardo-Veneto, the rule. The ruins and the surrounding forests are still in the possession of his descendants today.
