to bind them together. Dry stone structures are stable because of their unique construction method, which is characterized by the presence of a load-bearing facade of carefully selected interlocking stones. Dry stone technology is best known in the context of wall construction, but dry stone artwork, buildings, bridges, and other structures also exist.
Dry stone walls
A dry stone wall, also known as a dry stone dyke, drystane dyke, dry stone hedge, or rock fence is a wall that is constructed from stones without any mortarMortar (masonry)

to bind them together. As with other dry stone structures, the wall is held up by the interlocking of the stones. Such walls are used in building construction, as field boundaries, and on steep slopes as retaining walls for terracing.

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 that in their double wall architecture, the two portions of the walls incline into each other.

s cleared from the fields during preparation for agriculture (field stones) but many also from stone quarried nearby. For modern walls, quarried stone is almost always used. The type of wall built will depend on the nature of the stones available.
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 rows are composed of large flattish stones. 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. These have the effect of bonding what would otherwise be two thin walls leaning against each other, greatly increasing the strength of the wall. 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 cap stones span the entire width of the wall and prevent it breaking apart. 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 8 inches in height are called 'Bolt Holes' or 'Smoots'. Larger ones may be between eighteen and 24 inches in height, these are called a 'Cripple Hole'.
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

” or Welsh clawdd, which is a stone-clad earth bank topped by turf, scrub, or trees and characterised by a strict inward-curved 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. 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.
