Stone wall

Stone walls are a kind of masonry construction that has been used for thousands of years.

Later, mortar and plaster were used, especially in the construction of city walls, castles, and other fortifications before and during the Middle Ages.

Stone walls are usually made of local materials varying from limestone and flint to granite and sandstone.

However, the quality of building stone varies greatly, both in its endurance to weathering, resistance to water penetration and in its ability to be worked into regular shapes before construction.

These walls generally consist of a layered stone exterior and rubble infill.
