Abstract

One of the icons of Rzeszów is the 18th-century perspective view of the city, known as the Wiedemann plan. The view shows the buildings and topography of the city, which was then surrounded by a system of ponds and backwaters. All representative buildings have been preserved to this day, although in slightly changed forms. Ponds and backwaters do not exist.     The study described in the article was aimed at finding traces of the shores of these water reservoirs in the modern topography of the city, which is very much transformed. Maps and aerial photographs from the times when traces of the 18th-century topography were more visible were used for this purpose. The content of cartographic sources was used by overlaying digital versions of maps: historical and current, calibrating the image using a pair of points belonging to two distant objects with unchanged shapes. The information contained in the photograph was verified by making analogous geometric constructions on the photograph and on the current map. The culmination of the study was an in-situ reconnaissance. Many still clear traces of the former topography were found in the area, which may be imperceptible to an outside observer.     The obtained results introduce a correction to the Wiedemann’s plan, which mapped the spatial structure of the city partly incorrectly. They supplement the knowledge base about Rzeszów, which does not sufficiently cover spatial and urban issues. They draw attention to the ignored element of the urban cultural landscape, which is the topography, often insufficiently protected.
