With the development of cities, the planning and compositional construction of urban centers becomes more complex and spatially developed. This is due to the increase in the number of buildings forming the center and the expansion of their volume. Separate groups of buildings, alternating with squares and open green spaces, are interconnected by city highways and pedestrian crossings. The functional areas of the center acquire a certain degree of independence. In addition, the organization of crowded holiday demonstrations, military and sports parades and performances requires the allocation of developed areas and open spaces within the central region..
City centers arise and develop along with the emergence and growth of cities. An organizing role can be found in the ancient slave-owning cities of antiquity with their forums, including temples and commercial buildings, and in feudal cities, where the cathedral and trading squares stood out sharply among the ordinary buildings, and in the cities of the absolutism era, where the palace was located in the center — the residence of the ruler or administrative buildings serving the apparatus of state power. Historical urban public centers were distinguished by the content of the building, the location in the city plan, the style features and the scale of the buildings. The content of the building and the layout of the public center change in accordance with the development of the social life of society, but one common characteristic feature can be noted in the placement of public centers — their sharp separation from the rest of the city’s buildings.
