Natural stone walls are components of all ancient cultural landscapes. They were piled up 'dry', i.e. without mortar, and have fulfilled a wide variety of functions throughout history. They can simply be a demarcation to the neighboring property, so create protective and quiet zones, so for example also in cemeteries.

In the agricultural sector, typically in viticulture, steep slopes are terraced with walls, so that one comes to even cultivated areas. Or, as in very many regions in the world where pasture farming is practiced, dry stone walls have been built to enclose the pastures. For example, the stone-rich island of Öland in Sweden - it consists of a huge network of such natural stone walls. The fenced areas are less exposed to the wind, wild animals can not penetrate, and at the same time for the construction disturbing stones were removed from the areas where crops were grown.
