Liepāja as an industrial, commercial and resort city flourished at the end of the 19th century and at the beginning of the 20th century, thus promoting the development of architecture and garden art. The brilliant tsarist Russia engineers and architects from St. Petersburg were involved in the construction of the Navy town of Liepāja. On the other hand, the resort area and the city center was designed by architects and landscape artists from Brandenburg. The visual image of Liepaja center was formed through the interaction of two cultures, and it reflected the latest European architectural trends in city environment design of the corresponding period. An important role was assigned to greenery and landscape. Rose Square, designed in 1912, became the symbol of Liepaja. The center of Liepaja was reconstructed in 1970 and the original planning composition of the Rose Square was restored. However, there has been no research on the original intent and design of the Rose Square, the original selection of plantings, and the authors of the project. The main aim of this research: to analyze the green plantation planning and its impact on the visual image of Liepāja city center, as well as the architectural and spatial composition of the Rose Square before the Second World War. The main results: this research provides valuable information for future local territorial development plans, focusing attention on cultural values and identity. Material and methods: this study is based on research and analysis of cartographic, archive, and photo materials, as well as on a comparison of the use of rose plantations in German cities and Liepaja in the corresponding era.
