The wall stones is a particular type of wall built with suitably arranged and assembled stone blocks, without the use of binders or mortars of any kind.

The wall stones are made of local materials, including limestone, granite, sandstone and quartzite. The quality and type of wall stones for buildings vary greatly, in terms of product durability, resistance to water penetration and ability to be processed in regular shapes before construction.

In our days the wall stones with natural floor are very used mainly in containment of the slopes along the roads, traditional trait that distinguishes the northern parts of Italy.

In recent years, their usage with split surface is very popular along streams and rivers and confining walls.
