In areas of rocky soils around the world, farmers have often pulled large quantities of stone out of their fields to make farming easier and have stacked those stones to make walls that either mark the field boundary, or the property boundary, or both.

[[Retaining wall]]s resist movement of earth, stone, or water. They may be part of a building or external. The ground surface or water on one side of a retaining wall is typically higher than on the other side. A [[dike (construction)|dike]] is a retaining wall, as is a [[levee]], a load-bearing [[Foundation (engineering)|foundation]] wall, and a [[sea wall]].
