A palisade is a type of fence or wall made from wooden stakes or posts, often used for defense or to enclose an area. Historically, palisades were common in fortifications, providing protection against intruders or wild animals. They are typically tall and closely spaced to create a barrier that is difficult to breach. In addition to their defensive purpose, palisades can also serve as decorative elements in gardens or parks. Modern versions may use materials like metal or vinyl, but the basic concept remains the same. Palisades can enhance privacy and security while adding an aesthetic appeal to outdoor spaces.
