A villa courtyard with a wall-side flowing water landscape typically features a water feature integrated into the garden design, which runs along or near the walls of the villa. This can include a small pond, stream, or water channel, often designed to enhance the aesthetics and tranquility of the garden. Such water landscapes can be both functional, providing a natural habitat for aquatic plants and animals, and decorative, with features like stepping stones, bridges, or waterfalls. They require regular maintenance to ensure the health of the aquatic ecosystem and to keep the feature visually appealing.
