European Modernist Landscape Design refers to a movement in landscape architecture that emerged in the early 20th century. It emphasizes the integration of nature and the built environment, with a focus on simplicity, functionality, and the use of native plants. Key figures include Lancelot 'Capability' Brown, who is known for his 'English landscape' gardens, and later designers like Beatrix Jones Farrand and Lawrence Halprin, who influenced the field with their innovative approaches.
