The article considers the urban planning structure of the historical center of St. Petersburg as a hierarchy of ensembles. Urban ensemble compositions in the study are systematized regardless of their scale. The introduction presents the main problems of perceiving the city center as a system of interconnected ensembles. A brief review of relevant studies, domestic and foreign, is offered addressing the problems of the compositional and spatial structure organization of the city. The plan of J.-B.-A. Leblon 1717 as an example of a holistic urban ensemble is analyzed. The features of the existing hierarchical relationships are traced through the example of one vertical connection: the composition of the historical center, the composition of the Admiralty-Moscow side, the composition of the Five Axes of the Admiralty, the composition of Nevsky Prospect, the composition of Kazan Cathedral. For visualization purposes, the text description is supplemented by a figure illustrating the nature of the hierarchical relationships of the compositions. A 5-level hierarchical model of the environment of the historical center of St. Petersburg is developed and presented in the form of a table with the scale frames of each of the levels. The characteristic of integrity is proposed as a justification for the grouping of ensembles by levels. The conclusions suggest the features of the hierarchy of urban planning composition of the historical center of St. Petersburg: multi-levelness, vertical interconnectedness, large ranges of scale, totality of distribution, uneven distribution, gradual historical development.
