Defense Fence is a term used to describe a type of barrier or wall that is used for protection. The two most common types of defense fences are STOCKADE and PALISADE. STOCKADE is a type of fence made from wooden logs or posts that are placed close together and secured in the ground. PALISADE is a type of fence made from tall wooden stakes that are sharpened at the top and driven into the ground. Both types of defense fences are designed to provide protection from intruders.
