What is a "coping stone"?

A coping stone is a type of stone used to cover the top of a wall, providing protection and a finished look. These stones are typically flat and are designed to shed water, preventing it from seeping into the wall and causing damage. Coping stones can be made from various materials, including natural stone, concrete, or brick, and are often chosen for their durability and aesthetic appeal. They are commonly used on garden walls, retaining walls, and parapets, helping to enhance the overall design while serving a practical purpose in protecting the structure from the elements.
