The development of modern markets is characterized by a variety of architectural solutions and differs greatly from traditional ones. In this regard, the definition of the principles of the architectural organization of modern farmers' markets is of great importance now and in the future. The purpose of the study is to determine the basic principles of the architectural organization of modern farmers' markets. To achieve this goal, an analysis of domestic and foreign experience in the design and construction of modern farmers' markets was carried out. Research methods: the study of scientific, literary and journalistic sources and statistical data (including Internet sources) revealing the issues of the development of the architecture of the farmers’ market; the study of design, graphic and photographic materials characterizing the domestic and foreign practice of design and construction of the farmers’ market. As a result of the research, the following principles of forming the architecture of modern farmers' markets have been identified: the principle of universality, the principle of sustainability, the principle of gastronomy, the principle of openness and the principle of identity. These principles show that modern farmers' markets play an important role in the sustainable development of cities, stimulating the viability of public spaces
