What is an example of an artificial monument?

An artificial monument refers to a man-made structure that marks a boundary or signifies a particular location. Fences are a prime example of an artificial monument because they are constructed to serve specific purposes, such as delineating property lines or providing security. Unlike natural features like mountains, rivers, or rocks, which are created by natural processes, fences result from human intervention and design. They can be erected in various materials and styles, reflecting the needs and preferences of the property owner. Thus, fences distinctly fit the definition of an artificial monument, marking boundaries in a tangible and deliberate manner.
