Burg Schlaining was first mentioned in 1271 in a charter of Ottokar
Přemysl. At the time it was
known as a castrum Zloynuk and belonged to the counts of Güssing.
Schlaining Castle stood on a crossroads of major trade routes that
led through the Bernsteiner Mountains that lay to the North South.
After several changes of ownership, Burg Schlaining went into
possession of Emperor Frederick III. He pledged it to Franz
Batthyany in 1471. It stayed in the family until the 19th cetury. Last owner
of Burg Schlaining Ludwig Batthyany, former Prime
Minister of Hungary, was executed on October 6th, 1849. Burg
Schlaining subsequently passed to the Hungarian state.
Today Burg Schlaining houses a European Peace
Museum (part of the International Network of Museums for Peace) that
take two floors in the East Wing of Burg Schlaining. The motto for
the museum was chosen a quote of Alfred Nobel "If you want peace,
you must prepare for peace". It is subdivided into four categories:
environment, peace, war and violence.
