Considerable progress in the field of historical monuments protection was made after the Second World War; For various reasons, however, it could not protect many historical buildings from ruin and destruction. In compliance with the instructions given by Prime Minister and Ministry of Culture and Arts, departments where a number of institutions took charge of various historical buildings (especially the department of agriculture) remarkably increased their expenditures on repairs of historical monuments being in administration of their field branches. General Conservator of Monuments initiated a new form of protection of Polish cultural property: he suggested that historical buildings might be taken over by various institutions and adapted to their needs. As a result of this suggestion 140 historical buildings have been taken over so far. The next form of popularization of patronage by various institutions over the monuments was a competition for the best tenant of historical buildings organized in 1975. The jury awarded prizes and diplomas to 16 institutions patronizing historical buildings. First prize was awarded to the State Centre of Domestic Animals Insemination in Karczów, Voivodship of Opole, for repairs and adaptation as well as for the best keeping of the palace and garden complex from the turn of the 17th century, the Centre overhauled the palace at its own charge. Second prize was won by Gułtowy State Farm, Voivodship of Poznań, for repairs, preservation, interior decorations, adptaticn and outfit of the palace from the end of the 18th century at its own charge. Third prize was awarded ex aequo to the Institute of Zootechnics in Cracow (the Zator Section in Zator, Voivodship of Bielsko Biała) and to the Preventive and Sanatorium Treatment Centre in Moszna, Voivodship of Opole, for saving and adaptation of historical buildings according to conservation rules. Moreover, the jury awarded the social protector cf historical monuments who in 1975 took care of the ruined Tower in Chojna and overhauled it at his own charge. The above-mentioned forms of historical monuments protection will be carried on and popularized by the Board of Museums and Protection of Historical Monuments.
