1488-1493
Under the later Reichsfreiherr (Baron whose title has
been confirmed upon him by the German king) of
Stettenberg and Earls of Hardegg, Heinrich and Siegmund
Prüschenk, the Castle of Greinburg was erected between
1488 and 1493 as one of the first castles in the German-
speaking region.
1533
In 1533 the Imperial Counsel, Burgvogt (Governor of a
castle) of Enns and Landvogt (Governor of a territory) of
Swabia, Johann Leble (Löbl), acquired the Castle. Under
Leble (Löbl) the building received most of its present-
day form. In 1621 the Castle of Greinburg was sold to the
Earl Leonhard Helfrich of Meggau, who carried out basic
changes. A three storeyed, columned arcade became the
main feature for the appearance of the inner courtyard.
Furthermore, under Meggau the Sala terrena (so-called
stone theatre) was installed. In 1625 the "Rittersaal",
the Hall of Knights, and an adjoining chapel in the south
west tower were redecorated. Anna of Meggau brought
Castle and dominion of Grein into her marriage with her
husband, Earl Ludwig Sigmund of Dietrichstein.
1700
Since 1700 the owner of Greinburg was Earl Oktavian Karl
of Carioni, who sold the Castle to Franz Ferdinand of
Salburg and Prandegg in 1709.
1810
In 1810 the family of Dietrichstein became once again the
owners of Greinburg, however they sold the estate in 1811
to Josef Fink, the Mayor of Hainburg.
