Dry stone walling is the building of walls and structures without the use of cement or mortar. The skills stretch back over three millennia and include places like Skara Brae and the brochs in Scotland. Dry stone walls are common in upland areas of Britain where stone is much nearer the surface and soils thinner.
Many of the skills used by early wallers are still recognised and used today. The skill of the waller is being able to use the local stone to its best advantage. Today dry stone walling is prospering with an upsurge in interest in the environmental value of walls and the growth in prestigious garden, landscape and artistic projects.
Stones are placed lengthways into the wall to provide strength. Large stones are used for the base of the wall and the middle is filled with smaller stone as the wall goes up. Most walls have throughstones placed about half way up which tie both sides of the wall together and add strength to the structure. The profile of a wall is like a capital letter ‘A’, tapering towards the top. The wall is finished off with coping stones which can be done in a variety of styles and protect the wall from livestock and decay.
Most walls are built using the same basic techniques but it is the type of stone used that gives the walls their distinctive appearance. Some areas of the country do have different styles of building due to the nature of the stone, for example in far north of Scotland where some walls are built with large, single boulders and no small filling.
The Dry Stone Walling Association maintains a professional register of dry stone wallers on its website.
