Urban Environment during Post-War Reconstruction: Architectural Dominants and Nodal Points as Measures of Changes in an Urban Landscape

Abstract

Modernist planners were given the opportunity to apply the idea of the Modern Movement in the implementation of cities transforming after the World War II blitz, which was not possible before in long-term evolving structures. However, they could not alter everything: some urban and even architectural elements were necessary to be preserved. As a result, the elements of the ancient landscapes of these cities—historical objects and spaces—necessary for the continuity of evidence of history and identity were preserved, often being completely reconstructed. Finally, in some of these cities, both old and new elements contribute to the contemporary urban landscape. The aim of the research is to examine two key categories of urban structure in this perspective: (1) architectural dominants (landmarks) and (2) urban network nodes. For this purpose, (1) the changes in the number and rank of the spaces through which the landmarks expositions were carried out are compared, and (2) the changes in the rank of nodes in the urban structure, both these in the pre-war and in the present structures, as well as changes in their distribution and concentration areas are analyzed. The number of individual elements is compared and the changes in the structure of their arrangement are analyzed with the use of a polygon grid. A medium-scale European city (Bialystok) is used as the case study. Results of our analysis indicate that the post-war reconstruction led to a decrease in the number of elements of the urban grid (streets, nodal points), especially those of low rank. The rank of many others also decreased: 57% of all nodal points within the historical grid of the selected area does not exist in the post-war structure. The number of main rank directions of exposition decreased by 18% and in the subordinate group by 38%. The research is an attempt to construct a new criteria of evaluating changes in the quality of the cityscape, which is described in the article.
