Frequented by millions of Freemasons almost everywhere in the world, Masonic temples constitute an architectural and symbolic heritage of extraordinary richness, yet one that unfortunately remains largely unknown. Sometimes, it is even threatened by the decline in lodge membership, particularly in Anglo-Saxon countries. This study is the first of its kind, as it examines the various aspects of these buildings, from a symbolic, architectural, and social perspective. Originating from a single model, rooted in the legend of Hiram and the figure of Solomon's Temple in Jerusalem, Masonic temples adapt to the eras, locations, and cultures that produced them, demonstrating an extraordinary diversity of forms, styles, and scales. The book successively describes the Masonic temple as a symbolic object, and the architectural model that emerged from it, as it conformed to the codification of rituals in the 18th century, before addressing the architecture itself and its various interpretations across different countries and periods. It concludes with a chapter devoted to the Masonic temple's position within the social sphere and its visibility in the city, and what this position reveals about the place of Freemasonry in the societies where it is accepted.
