Natural stone has been used as an available and accessible material  in objects and buildings and has accompanied the man from the prehistoric period until now. This raw material has been recording the history of civilizations. Initially was used  in a rough form and gradually turned  into delicate and profuse ornamental art.

Masonry work is the technique that transforms the stone either by hand or with appropriate tools and presents it ready to be used in buildings and other facilities and equipments. It can be either used  as a structural element, or as a decorative element and often serves both functions.

Masonry and stonework is the technique of cutting and preparing the rocks and stones for construction, with decorative and structural effects. It is one of the oldest building techniques. Great master pieces, such as cathedrals, bridges and castles were built using this technique.

A building carried out with masonry stone can either use mortar as a bound element or can be performed in a dry stone style . What differentiates the masonry from other rudimentary techniques of construction with stone, it is the exact  accuracy that  the blocks are cut. The angles may be either 90 degrees ( for square ) and with other pre-defined values, always seeking the best fit and stability.

Etymologically the word masonry in Portuguese originates from the expression "canto" / corner, and the experts working on this art are called  "canteiros" / stone masons. The association to the word corner (angle) shows the most important goal of the stone: to prepare the stone for use as a design element.

As a decorative element, the rocks are detailed and carefully sculpted , before becoming part of the construction. These are true sculptures that have no existence  independently of the building where they belong.
