A courtyard is an open space surrounded by the walls or buildings of a structure, often found in residential, commercial, or institutional settings. It serves as a private area for relaxation, social gatherings, or outdoor activities. Courtyards can vary in size and design, featuring gardens, seating areas, or pathways. Historically, courtyards have been integral to architectural styles, such as in Mediterranean or Spanish homes, where they provide natural light and ventilation. They can also be seen in castles and palaces, where they served as central gathering places for residents and visitors alike.
