The manor house was built between 1910 and 1913 by the Prussian Count Valentin von Ballestrem on land that his father Franz von Ballestrem had once purchased from the original owner, Arnold Popper, with the intention of building an occasional representative seat here. In 1973, the manor house in Oščadnica, together with the adjacent forest park covering an area of more than 3 hectares, was declared a National Cultural Monument of the Slovak Republic within the Kysuce Protected Landscape Area. At present, it is owned by the Žilina Self-Governing Region and is also the seat of the Kysuce Gallery in Oščadnica. The first exhibitions in the building were opened to the public in November 1981.
The manor house underwent a vast reconstruction in 2020 – 2022, thanks to which new exhibition spaces were created, and the building acquired a well-deserved representative appearance. A barrier-free entrance was also built at that time. The gallery currently administers more than 3,000 works of art and focuses its acquisition activities on contemporary art with an emphasis on the work of representatives of the Kysuce region and the work of significant representatives of Slovak fine arts. In the past, the gallery organised international sculpture symposia, attended by artists from abroad. The works created during these events became part of the forest park.
The manor house does not serve as an exhibition of historical furniture or a collection related to its past. Instead, it is an exceptional space dedicated to art and, thanks to its architectural style, it represents a unique monument of its kind in the Kysuce region. History and the present are thus combined in one place. Openings, exhibitions and concerts are held in the manor house, and cultural and social events are often moved to the adjacent forest park.
