The chronicles of the Schreiberhuber Farm & Forest Estate encompass the closely intertwined histories of three farms, family-owned for more than 700 years: Plassgut at Ansfelden, Auhof Residence at Kremsmünster and Summerauerhof at St. Florian.

The first documented farming ancestor of the Schreiberhuber family was Ulrich von Summerau, who was mentioned as “Ulricus de Summerau” in 1413 at the Sumerauerhof in the St. Florian monastery chronicle.

The best known of the barons of Summerau were the provincial judge of the province of Austria ob der Enns (iudex Austriae superioris), who resided at Ennsburg Castle in Enns from 1264 onwards.

Konrad von Summerau, who is considered the first governor of Upper Austria,

Anton Thaddäus von Summerau (from 1753 first President of the Government of Lower Austria) and his nephew

Joseph Thaddäus von Summerau, who was the last President of the Government of Lower Austria from 1791.

1822

Emperor Franz I of Austria guides his ally Czar Alexander I from Russia in the course of a joint Austria trip to Ansfelden to show him the prosperous agricultural enterprises of his subjects, reports the German travel writer and municipal librarian of Bremen, Johann Georg Kohl, in his 1842 work “Reiseberichte über Österreich, das bayrische Hochland, Dänemark und Großbritannien”.

1874

After twelve years, the newly built Plassgut Estate is completed as it appears today, epitomising an architectural blend of classicist Baroque / Josephinism.

The Ritzlhof Manor, located in Ansfelden, which belonged to Michael Schreiberhuber in 1817, served as the model for the building. In 1875, the Ritzlhof Manor was taken over by the Austro-Hungarian dual monarchy and transformed into a state agricultural facility and fruit orchard.
