is still a lane called Cossack). These settlements, which eventually merged with the suburban development into a single planning structure, initially had a picturesque, free tracing of the street network. But, if over time the layout of the Balka was subjected to only partial regulation, then only small fragments remained of the original layout of Kovalevka (Bebel St., Transportnaya St., Molodezhny Lane). Almost simultaneously with the appearance of the suburb, the following were built: the city market (on the site of an existing shopping center), the wooden Assumption Church (on the site of the regional committee of the Communist Party of Ukraine), the wooden Vladimirskaya (Greek Church), the wooden Znamenskaya Church (on Bykovo), the schismatic prayer house. These objects with ordinary, mainly wooden manor buildings, as well as with fortress structures, determined the appearance of the city in the first ten years of its development. The planning architectural and spatial composition of the central part of the settlement consisted in the hierarchical subordination of its main street (B. Perspektivnaya, K. Marksa) with the square on it and ordinary low-rise buildings. Among this development, public houses and shops were sharp accents, and the Assumption and Vladimir churches served as dominants. The street served as the main axis of the entire composition. It divided the suburb into two equal parts and the direction of its route almost coincided with the center of the fortress. Thus, the fortress with the church in it turned into the third main dominant of the street, although it was located outside its boundaries. In plan, the area was rectangular with an aspect ratio of 1:3 (50x150 m.). On one of the smaller sides, it adjoined the main street (Bolshaya Perspektivnaya), and on the wide side it adjoined the market and a small quarter, like the square, which is now included in the territory of the market. From the side of the market on the square there were a gostiny dvor and butcher shops, and on the opposite and smaller sides - public buildings. Within the retranchement, the city occupied an area of 2.3 sq. km. (1.8 x 1.5 km.). From the period of the formation of the city the fortress of St. Elizabeth was the town-planning core of the settlement, the place of concentration or attraction of all its main functions. The central administrative function was concentrated in the fortress. This is the administrative management of the
