FORTIFICATION OBIECTS AND STREET NETWORK DEVELOPMENT IN THE HISTORICAL PART OF CHERNIVTSI CITY IN THE 18th-20th CENTURIES

Formation and development of the central part of Chernivtsi is a long historical process. The settlement, which emerged in the XIV century, underwent major urban transformations that took place during the XVIII-XX centuries. They became an important period of creation of the renewed structure plan of the city area which is still in operation. The historical city centre has been changing its structure, size, functional organization during a long time. The objective of the research is to study and compare the main parameters and characteristics of the city at certain historical stages by analysing the development of its transport network. The purpose of the article is to review and analyse available cartographic materials and study the street network development in the historical part of the city in the late XVIII - XX centuries. The article highlights the factors that played an important role in the formation and development of Chernivtsi city centre, in particular, strengthening and expansion of economic ties. According to the findings, discovery of new trade routes became a decisive factor that influenced the development of Chernivtsi, determined the city structure and directions of the main streets. Other important factors include natural conditions and local terrain, social economic and administrative impact. Studies have shown that the historical centre of Chernivtsi evolved according to the existing structure plan. Analysis of cartographic materials and historical sources allows to characterize the basic principles of urban development. Expansion of the street network and squares, as well as trends in the planning of residential areas provide an opportunity to assess their nature, scale and size. Topographical maps enabled us to devise comparative schemes of urban development and evolution of city boundaries throughout the studied period. The city center moved gradually to new areas in the south-western direction. This feature of the city development provides important materials for urban study. This work can be primarily aimed at studying the urban planning structure, defense lines, public spaces, etc. The city developed in an extensive way, pushing the boundaries of the city center, creating new parallel urban complexes with new central squares. The most difficult task for scientists today is to localize these boundaries for different stages. The next difficult task is to find out old defense systems existed in the different parts of the city in the past. A completely unresolved question is how defense complexes influenced the development of the planning structure. The study allowed to highlight the prerequisites for major urban transformations in the historical part of Chernivtsi in the XVIII - XX centuries.
