History
Burg Altaist is a former medieval hilltop castle in Austria, originating around 1050 on Altaistberg. Also known as Alt-Aist or Altenaist, it served with Burg Neuaist as a seat of the Lords of Aist, a noble family associated with several castles in the region.
The Lords of Aist and the Babenbergs
Burg Neuaist, about 2 kilometres north in Pregarten, is regarded as another castle of the same family. In the thirteenth century, Burg Altaist passed into the possession of the Babenbergs, the medieval dynasty that ruled the margraviate and later duchy of Austria before the rise of the Habsburgs. Documentary references to the castle cease from that century onward, suggesting that it subsequently fell into decay.
The name Altaist and archaeological evidence
The name Altaist probably became established during the eighteenth century. The area had already been associated in the late Middle Ages with the name “on the old Aist.” A cadastral and rural municipality called Altaist was created in 1785 and was incorporated into Ried in der Riedmark in 1938.
Excavations recovered a pfennig, a medieval coin denomination used in German-speaking Central Europe, from the Krems mint. The coin dates to the final years of Leopold III or the period of Leopold IV, both Babenberg margraves of Austria, and is regarded as the oldest medieval coin find in the Mühlviertel, a historical region of northern Upper Austria. The site has no monument protection.
Remains
Castle layout and defences
Only a Burgstall, meaning the archaeological site of a former castle without substantial standing buildings, survives at Burg Altaist. The remains occupy the summit of Altaistberg at approximately 463 metres. A stone perimeter wall encloses the summit plateau, while a lower inner ditch and an outer rampart lie below it. The site stands beside the B123 road between Mauthausen and Pregarten. From the summit, the land opens northward across the Feldaist depression; the Riederbach rises south of the site and flows into the Gusen farther west.
Archaeological finds and traditional identification
Ceramics from the site span approximately 1050 to 1250, with a concentration in the second half of the twelfth century. Excavations also recovered scabbard fittings. House Altaist No. 1 is traditionally believed to contain the former castle dungeon, linking the surviving domestic building with the earlier castle site.
