The article is concerned with the anthropology of a city. As an instrument of conceptualization, we used a three-dimensional scheme: organization — communication — information, which allows giving the urban interpretation for each of the coordinates, and then, using the two-dimensional projections (organization-information, organization-communication, information-communication), to develop a concept of the three-dimensional image of city. It has been proposed to distinguish three types of organizational structures when considering the city as an organization: hierarchical, algorithmic, and relational. The necessity of curbing the growth of the city and solidating it in the context of communication has produced a number of projections. One of them, "A compact city or city of short distances" has been considered. The concept of a compact city is based on the cost-effective public transport system, and it encourages pedestrian traffic and cycling. When considering the city as an organization, the main focus lies on its structure. From a topological point of view, it has been proposed to distinguish between three types of such structures: hierarchical, algorithmic, and relational. A hierarchical structure represents a tree of power hierarchy, but its content is not necessarily associated with consistent delegation of authority power (from top to bottom) or gradual accumulation of information (from the bottom up). Thus, a library catalogue, as well as other classification means, is arranged on the principle of hierarchy. An algorithmic structure is a scheme of production process which consists of a set of sequential operations. Its mathematical model appears as a network diagram. Typical examples of such structures include an algorithm of construction of a building, from foundation to roof, a conveyed assembly of complex technical devices, etc. In relation to a city, this structure can be filled with different content. Thus, carrying out of repair and maintenance in one of the city networks often requires not only formal coordination, but also a network schedule of joint work with other community services (water, electricity grid, heating, communication lines, etc.). A relational structure is a group of objects of arbitrary nature, usually of the same type, singled out from the total quantity of objects on the basis of any common feature. A complex of educational or medical institutions, trade companies, domestic services, etc. could be an example of such group within the organizational structure of a city.
