History+
As early as 1263, during the Bohemian rule under King Ottokar II, a small fortification, the “Castrum Prukke,” existed on the Brucker Schlossberg. Originally owned by the Eppensteiners, it was probably administered by Herbord von Füllenstein, also known as Herbord von Bruck. He was a seneschal to the royal governor Bishop Bruno of Olomouc and possibly a city and castle captain. In 1268, Hermann von Krottendorf is mentioned as another castle captain, indicating that the fortress was expanded during the new establishment of Bruck. A lost document suggests that the fortress already existed around 1112. The castle was a princely fief of St. Lambrecht Abbey and was often managed by minor nobles such as the Krottendorfers or Gaalers, or pledged to nobles and citizens, including Hans Klemm d. J. in 1345 and Pankraz Kornmeß in 1505. Since 1461, the castle has borne the name Landskron. During the Hungarian War (1460), an imperial caretaker with soldiers was stationed there.
