Detailed field investigations are of key importance to the restoration of neglected and dilapidated historical parks, enabling the identification of former compositional structures. A careful analysis of the existing vegetation forms a basis for the interpretation of spatial conditions. Equally invaluable in confirming the existence of these are the memories of the former owners, vintage family photographs, or artists’ impressions. Canvases by Jacek Malczewski, one of the most outstanding Polish artists, are an example of just such an historical record. This paper presents an investigation to identify the original composition of the park in Wielgie based on field studies and the interpretation of works by Jacek Malczewski.
