The architecture of the Masonic temples is a living heritage, but little studied, particularly in the context of academic research. Yet it has two advantages. As an object of study, first of all, it offers formal, spatial and sufficiently significant stylistic characteristics that we may wish to describe, seeking both to define the limits and invariants and also to identify different variations across tropisms related to history, geography or the culture in which it develops. This architecture offers also an interest as a subject of research: it is strictlydictated by specific rituals that define both form, organization and use. From this perspective, this study provides first revisit the concepts of type and model, as they were defined within the framework of the typo-morphological analysis developed by the Italian criticism in the 1970s. It establishes also a link between the use, here codifiedrituals, and architectural form, and suggest the outlines of a theory of concretion, within the form of architectural spaces would be understood as the result of ritualized practices of space. The thesis is developed in three parts. The first part, which opens a state ofknowledge, is devoted to the methodological approach and research developments, thanks to the means of digital technology and computers, which enabled the developmentof the corpus of research. The second part is devoted to the analysis of this corpus, based on the social, architectural and symbolic aspects of the Masonic Temple. The third part provides an extract of the of the corpus. This excerpt covers Europe and North America.
