[1] The palace, built in classical style was an early work of Karl Friedrich Schinkel.
The Owińska estate, which was owned by the local Cistercian convent and included several nearby villages was confiscated and sone 12,000 hectares of whish was transferred to Sigmund Otto Joseph von Treskow [de], who invested considerable funds into the development of the whole property, including the renovation of the palace.
On the occasion of the anniversary of Schinkel in 1985, Polish cultural heritage protection authorities arranged some renovation of the building.
After the fall of Communism the building was privatized, left unused, and fell into disrepair, in particular, due to theft and vandalism.
Polish television, Frankfurter Allgemeine Zeitung, the Polish embassy in Berlin and the Ministry of Culture in Warsaw drew an attention to the sorry state of the affairs, and eventually a private German businessman Claus Queck from Düren arranged a consortium to save the complex.
