uses the classic Inca architectural style of polished dry stone walls of regular shape. The Incas were masters of this technique, in which blocks of stone are cut to fit together tightly without mortar. Many junctions are so perfect that not even a knife fits between the stones. The structures have persisted in the high earthquake region because of the flexibility of the walls, and because in their double wall architecture, the two portions of the walls incline into each other.
Construction
The style and method of construction of a wall will vary, depending on the type of stone available, its intended use and local tradition. Many older walls were constructed from stones and boulders cleared from the fields during preparation for agriculture (''field stones'') although some used stone quarried nearby. For modern walls, quarried stone is almost always used.
One type of wall is called a "double" wall and is constructed by placing two rows of stones along the boundary to be walled. The foundation stones are ideally set into the ground so as to rest firmly on the subsoil. The rows are composed of large flattish stones, diminishing in size as the wall rises. Smaller stones may be used as chocks in areas where the natural stone shape is more rounded. The walls are built up to the desired height layer-by-layer (''course by course'') and, at intervals, large tie-stones or ''through stones'' are placed which span both faces of the wall and sometimes project. These have the effect of bonding what would otherwise be two thin walls leaning against each other, greatly increasing the strength of the wall. Diminishing the width of the wall as it gets higher, as traditionally done in Britain, also strengthens the wall considerably. The voids between the facing stones are carefully packed with smaller stones (''filling'', ''hearting'').
The final layer on the top of the wall also consists of large stones, called ''capstones'', ''coping stones'' or ''copes''. As with the tie stones, the capstones span the entire width of the wall and prevent it breaking apart. In some areas, such as South Wales, there is a tradition of placing the coping stones on a final layer of flat stones slightly wider than the top of the wall proper (''coverbands'').
In addition to gates, a wall may contain smaller purposely built gaps for the passage or control of wildlife and
livestock

such as sheep. The smaller holes usually no more than in height are called "Bolt Holes" or "Smoots". Larger ones may be between in height, which are called "Cripple Holes".
Boulder walls are a type of single wall in which the wall consists primarily of large boulders, around which smaller stones are placed. Single walls work best with large, flatter stones. Ideally, the largest stones are being placed at the bottom and the whole wall tapers toward the top. Sometimes a row of capstones completes the top of a wall, with the long rectangular side of each capstone perpendicular to the wall alignment.

Galloway ( ; sco, Gallowa; la, Gallovidia) is a region in southwestern Scotland comprising the counties of Scotland, historic counties of Wigtownshire and Kirkcudbrightshire. It is administered as part of the council areas of Scotland, counci ...
dykes consist of a base of double-wall construction or larger boulders with single-wall construction above. They appear to be rickety, with many holes, which deters livestock (and people) from attempting to cross them. These dykes are principally found in locations with exceptionally high winds, where a solid wall might be at risk of being unsettled by the buffeting. The porous nature of the wall significantly reduces wind force but takes greater skill to construct. They are also found in grazing areas where they are used to maximize the utility of the available stones (where ploughing was not turning up ever more stones).
Another variation is the Cornish hedge or Welsh ''clawdd'', which is a stone-clad earth bank topped by turf, scrub, or trees and characterised by a strict inward-curved
batter
Batter or batters may refer to:
Common meanings
* Batter (cooking), thin dough that can be easily poured into a pan
* Batter (baseball), person whose turn it is to face the pitcher
* Batter (cricket), a player who is currently batting
* Batter ...
(the slope of the "hedge"). As with many other varieties of wall, the height is the same as the width of the base, and the top is half the base width.
Different regions have made minor modifications to the general method of construction—sometimes because of limitations of building material available, but also to create a look that is distinctive for that area. Whichever method is used to build a dry stone wall, considerable skill is required. Correcting any mistakes invariably means disassembling down to the level of the error. Selection of the correct stone for every position in the wall makes an enormous difference to the lifetime of the finished product, and a skilled waller will take time making the selection.
As with many older crafts, skilled wallers, today, are few in number. With the advent of modern wire fencing, fields can be fenced with much less time and expense using wire than using stone walls; however, the initial expense of building dykes is offset by their sturdiness and consequent long, low-maintenance lifetimes. As a result of the increasing appreciation of the landscape and heritage value of dry stone walls, wallers remain in demand, as do the walls themselves. A nationally recognised certification scheme is operated in the UK by the Dry Stone Walling Association, with four grades from Initial to Master Craftsman.

Environmental benefits
Dry stone walls are important biotopes for numerous plants and animals. The cracks are home to special plant communities that have adapted to the extreme conditions of the terrain. They are also valuable habitats for various thermophilic animal species, such as lizards, common toads, wild bees and beetles.
Dry stone walls in terraced crops help to protect the soil by reducing soil erosion caused by water. Rainfall slowly seeps into the ground behind the dry stone wall so that the plant roots can gradually absorb the soil water and surface runoff is reduced. As the masonry of a dry stone wall is not filled with mortar, water can escape between the stones without exerting much pressure on the masonry in case of continuous precipitation, which leads to the saturation of the ground space.
An important conservation goal is to preserve dry stone walls in a traditionally cultivated landscape. Many dry stone walls have been lost, especially as a result of land consolidation measures, which often mean the redevelopment of entire field corridors. To compensate, gabions are sometimes built, but according to some experts they are not an equal substitute for dry stone walls in terms of nature conservation.
An indirect environmental advantage is that dry stone walls can in principle be built without the use of external materials such as cement, sand and metal, or external energy. Only with high walls from 5 m this advantage disappears, as other techniques often require much less material or work.
Other uses
While the dry stone technique is most commonly used for the construction of double-wall stone walls and single-wall retaining terracing, dry stone sculptures, buildings, fortifications, bridges, and other structures also exist.

, Sweden), Maiden Castle, North Yorkshire, Reeth, Dunlough Castle in southwest Ireland and the rampart of the Long Scar Dyke. Many of the dry-stone walls that exist today in Scotland can be dated to the 14th century or earlier when they were built to divide fields and retain livestock. Some extremely well built examples are found on the lands of Muchalls Castle.
Dry stone walls can be built against embankments or even vertical terraces. If they are subjected to lateral earth pressure, they are retaining walls of the type gravity wall. The weight of the stones resists the pressure from the retained soil, including any surcharges, and the friction between the stones causes most of them to act as if being a monolithic gravity wall of the same weight. Dry stone retaining walls were once built in great numbers for agricultural terracing and also to carry paths, roads and railways. Although dry stone is seldom used for these purposes today, a great many are still in use and maintained. New ones are often built in gardens and nature conservation areas. Dry stone retaining structures continue to be a subject of research.
