Abstract. The appearance of the resort towns of the Caucasian Mineral Waters, formed during the 19th - 20th centuries, was determined by remarkable monuments of architecture and landscape architecture, dating back to the traditions and forms of ancient Greece and Rome. Rational, respectable and aesthetic order forms of Classicism determined its wide typological applicability and during the 19th-20th centuries they continued to form significant urban planning and park ensembles. When creating resort facilities, architectural monuments of antiquity are models for studying, repeating and interpreting the methods of organic inclusion in the natural environment. The article examines the importance of ancient forms in the process of formation of the cities of the Caucasian Mineral Waters resort. A full-scale survey of two objects selected for study, typologically and stylistically different, was carried out – the architectural structure of the mud baths in the city of Essentuki and the monument of landscape art – the park's Main Staircase of the sanatorium named after S. Ordzhonikidze. Literary sources were studied, landscape-visual and compositional analysis of objects was carried out. The first object – a mud bath in the city of Essentuki – a medical building, one of the most famous architectural monuments of the city of the eclectic period, was built according to the project of the architect Eugene Shretter. The second object is the famous Main Staircase of the sanatorium named after S. Ordzhonikidze in the city of Kislovodsk, built by the architect – constructivist Ivan Leonidov, is an object of cultural heritage of federal significance – a monument of urban planning and architecture. The analysis showed that ancient forms successfully pass the test of time, change of political systems and social conditions, are able to transform plastically and functionally under the influence of stylistic changes and today retain their attractiveness and relevance.
