Hollenegg Castle in Bad Schwanberg, Styria, is a complex historic fortress combining medieval, Renaissance, and Baroque architectural elements developed over many centuries. First documented in 1163 in Admont Abbey records, archaeological evidence indicates human occupation dating to 3900 BC, reflecting its strategic position on a rocky spur above the Lassnitz River. It served as the administrative center for the Archdiocese of Salzburg's West Styrian lands until 1803 and has been held by the Liechtenstein family since 1821. Today, the castle functions as a contemporary design and arts center hosting rotating exhibitions within its historic rooms and courtyards.
