A wall is a solid structure that divides or encloses an area. It can be made of various materials like brick, wood, or concrete. Walls are commonly found in buildings, providing support and privacy. They can also serve decorative purposes, enhancing the overall look of a room or outdoor space. In addition to buildings, walls can be found in nature, such as the steep cliffs of a mountain or the barriers of a canyon. People often use walls to create boundaries, whether in homes or gardens. They can symbolize protection, separation, or even confinement, depending on their context.
