Abstract: The subject of the study is the Seljuk cultural code in the cultural landscape of the Crimea. The object of the study is the Seljuk style in the decorative and applied arts and architecture of the Crimea. The article uses the following methods: culturological (ontological and semiotic) analysis in deciphering the meanings of Seljuk elements, the method of historicism in the ontology of Seljuks in the Crimea, the method of analysis of previous studies, the method of synthesis in the identification of ethnic signs. The article discusses the following aspects of the topic: The semantics of the Seljuk code in the cultural landscape of the Crimea is revealed, examples and ways of applying Seljuk stylistics in decorative and applied art and architectural decor of modern and postmodern are considered. 1. The multinational cultural landscape of Crimea consists of the cultures of ethnic groups that inhabited the Crimea in different periods. The leading marker of the definition and self-determination of ethnic groups is religion and folk mythology, embodied in national traditions. A clear example demonstrating ethnic identity and its continuity is folk art. 2. The appearance of the Seljuks in Crimea and the wide spread of the Seljuk style, which has become one of the main components of the "Crimean style" in modern and postmodern architecture, is not accidental and is due to centuries-old ethnic migrations and the mutual influence of cultures. The Seljuk style, therefore, ceases to be purely ethnic, and becomes part of the cultural landscape of the Crimea, used in the decor regardless of the ethnic origin of the author / owner. 3. A special contribution of the authors to the study is the identification and justification of the Seljuk code as one of the main ones in the Crimean stylistics. The scientific novelty of the research consists in the semiotic and stylistic analysis of the Seljuk code in the cultural landscape of the Crimea.
