The article is devoted to the study of spatial planning structures of museum and cultural complexes based on spatial and configurational analysis. The author proposes a re-search methodology based on the methods of spatial analysis and syntax. Features of the spatial analysis of interiors on the examples of museum and cultural complexes are considered. It was found that all of them at the present stage have a tendency to form or deepen the degree of integration: the enfilade, didactic model (British Museum) is supplemented by an integrated core, turning into a more democratic one; multiaxial, lattice models form such centers at the intersection of axes, centric models deepen the social aspects of the integrated core.
 The exposition of museums of history and nature is usually placed perimeterally and sequentially (in accordance with a certain historical period), has a linear configuration that does not provide for bridges of meetings, except for the entrance hall. Instead, the interior space of museums of modern art is mostly integral, democratic, integrated, provides one or more meeting places; exhibition rooms and the lobby are connected by a system of stairs and transitions, sometimes on different levels, forming a complete system of internal space.
 A spatial analysis of the configurations of Alvar Aalto's libraries showed that they, as a rule, contain a central integrated core, which turns them into public centers to this day. At the same time, it was determined that the majority of museums in Kyiv have a historical complex, didactic planning model that needs updating from the point of view of improving the experience of visitors and greater democratization of the movement.
