Książ Castle (Zamek Książ)

Książ Castle (Zamek Książ) is a large historic castle complex overlooking the gorge of the Pełcznica river north of the city of Wałbrzych in Lower Silesia. Its history is described in tourist and heritage sources as dating back to the medieval period (with references to origins as early as the 13th century) and it is presented as the largest castle in the Silesia region and among the largest in Poland. The castle sits within Książ Landscape Park in the Sudeten foothills and is a prominent regional tourist attraction. The site's modern notoriety in popular media and local memory is closely connected to wartime history and subterranean constructions in the Wałbrzych region. Multiple sources document that Germans carried out extensive wartime activity in the mountainous area, including creation of tunnel systems, and that a persistent local legend holds an armoured train from the Breslau (Wrocław) area — reportedly laden with valuables — was driven into a hillside tunnel near a medieval castle in the Wałbrzych area during the final days of World War II and never emerged. The legend has spurred decades of searches by private treasure hunters and occasional official interest. In 2015–2016 the legend attracted renewed attention when media reports described claims (including a reported deathbed confession) that led to ground-penetrating radar investigations and statements by officials. Press accounts quoted Poland's deputy culture minister Piotr Żuchowski reporting that GPR had produced images interpreted by some as consistent with a buried train near Wałbrzych, and in September 2015 the Polish military sealed off an alleged site in the Wałbrzych area. These items are reported by the press and described in the sources as leads, media claims, and investigatory actions rather than confirmed recovery of the train or associated treasure. The identity of the alleged deathbed confessor is not provided in the sources cited here. No sources provided in the research notes describe classical paranormal phenomena (such as apparitions or poltergeist activity) or name spirits associated with Książ Castle; the primary folkloric element in the supplied material is the wartime 'armoured/gold train' legend and the related subterranean/tunnel narratives that link local history, wartime secrecy, and treasure-seeking activity.
