For the development of projects of new orbital stations with a crew of several dozen people, the formation of new principles of space architecture is topical. The process of the emergence, formation and development of public space in traditional culture is presented. The principles and techniques of the semantic organization of public space developed by culture over many millennia and which have become the basis in the system of perception of this type of space by man and society are shown. A number of examples of implemented and projected manned orbital stations show the emerging process of formation in their structure of public space. Some possible options for the prospective development of this type of spaces have been developed and presented.
