Survey monuments physically mark a property's perimeter boundary, usually corners, angles, curves or bends. They take the form of iron bars manually hammered into the ground, or cut crosses - etched in curbs or sidewalks. In all cases they represent a surveyor's professional opinion as to the physical location of a property's boundary. The monuments mark the boundaries. Note that they are sometimes are off-set from the true location. In these cases they are called witness monuments that reference a corner location where the monument could not be physically set.

Why is this important?
Survey monuments are official boundary markers - usually iron bars manually hammered into the ground. Identifying and finding these original, undisturbed markers provides you with the most accurate physical evidence of your boundary.
