Before World War II, the manor and park complex in Piotrowice was owned by Roman Gustowski. After the over 270-hectare estate was taken over for the purposes of land reform in 1945, the manor quickly fell into disrepair and was demolished in the 1960s. However, it survived in the memories of people who frequented the manor in the interwar period, for example, as kindergarteners for tea and cookies at Mrs. Gustowska’s. Those who are more persistent could even still find the manor’s staircase, which was used to go down to the park, and which today would offer a beautiful view of Slupeckie Lake below.
