Around 1130 Tannbach first appeared in written documents: Heinric de Tanebach, probably a feudatory from the Griesbach family, appears in one document from the Göttweig monastery as a witness. Only 150 years later, Ulrich Galsperger is mentioned as the owner. In the middle of the

15th century Tannbach was the property of Mathes Kienast and remained in the family until 1527. It was then owned by Freistadt Mayor Hans Weissenauer and then by his son.

Ernst Hack von Bornimb, who came from an old Brandenburg noble family, moved to Austria in

1550 and acquired Tannbach for a few years as his first holding in the region. 1553 King Ferdinand I gave Hanns Kurz a court in Tannbach as fief. He was a salt producer over Enns for a short time. Thanks to his loyal service, and as a compensation, his sons Hans Christoph and Wolf achieved the liberation of their property from fief duties. Tannbach now became a free noble residence and was rebuilt into a castle. Eventually, the property returned to Ernst Hack von Bornimb. In the last quarter of the 16th century, he rebuilt it in Renaissance style.

By 1595, although with a 20-year break, the castle remained in the possession of the family until Hanns Georg Hack von Bornimb sold Tannbach to Hieronym von Neideck. The aristocratic residence now included a courtyard, brewery, hop garden, court tavern, land, a fruit garden, and milling rights. For the next 300 years, the owners often changed, but did little for the building’s maintenance.

1798 the estate was under the supervision of court insolvency administrators. 1873 Tannbach was assumed by cartographer and lieutenant colonel Josef von Scheda, who rebuilt it in a Neo-Renaissance style. 1906 the estate’s operation passed to Count Ludwig von Polzer-Hoditz and Wolframitz and his wife.2006 Tannbach Castle was acquired by Johannes Weissengruber.
