Fences

A fence is a freestanding structure designed to restrict or prevent movement across a boundary. Fences are generally distinguished from walls by the lightness of their construction and their purpose. Walls are usually barriers made from solid brick or concrete, blocking vision as well as passage, while fences are used more frequently to provide visual sectioning of spaces.
Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).
