A sunken garden, also known as a sunken bed or depression garden, is a type of garden design featuring a garden area lower than the surrounding ground level. This design can create a sense of intimacy and privacy. The American sunken garden illustration would depict the layout and elements of such a garden, including plants, pathways, and features like fountains or seats. Sunken gardens often incorporate features like stepped terraces, walls, or raised beds to enhance the visual appeal and functionality.
