the loss of 58 chests with archaeological relics, five chests from the African collections and an unidentifiable number of militaria, city souvenirs, handicraft products and numismatic items. Post war period After Bydgoszcz liberation, the city authorities moved the seat of the museum into the 19th century edifice located at 4 Gdańska street, which had harboured until 1937 a 70-bed Municipal Hospital and from 1938 to 1945 the Municipal Department of Social Welfare (). On 11 April 1946 the City Museum was opened in the new building and named after Leon Wyczółkowski. Kazimierz Borucki, ex-museum custodian, was appointed director of the institution. At the time, the first floor was used as a picture gallery, while city memorabilia and archaeological relics were located in ground floor rooms. In the 1940s, a public call to recover Museum items lost during the war was carried out, which helped to gather back several historic objects disseminated. In 1949, the museum was nationalized and in 1975, was transformed into a District Museum, covering the entire area of the newly created Bydgoszcz Voivodeship. As time passed, it was necessary to expand Museum capacity with new buildings to fit the growing number of exhibits. Several solutions were considered. One of them was to build a new seat of the museum as part of an ambitious plan, designed by Włodzimierz Padlewski (1903-2007) from Sopot, to rebuilt the lost western frontage of the Old Market Square: unfortunately, this project was never implemented. The solution adopted by city authorities lay in using the ancient watermills on Grodzka Street: a comprehensive renovation, ended in July 1964, aimed at suiting the needs of the museum. The buildings were then handed over to the latter in 1975. In the post-war period, mainly collections grew in quality and quantity, be it historical items related to the past of the city or artistic and guild craftsmanship, numismatic and archaeological collections. In particular, the museum constituted a collection of contemporary Polish art with a significant role on the national cultural landscape. After 1990, the museum was taken over back by municipal authorities. From 1993 on, several granaries across the town have been used: those on the Brda river welcome exhibitions related to the history of Bydgoszcz, while in the White Granary on Mill Island (), a permanent craft exhibition has been presented. Between 1993 and 2006, a major renovation was carried out upon the granaries in Grodzka
