Stonemasonry, also called stonecraft, is the skilled practice of shaping and arranging stone.

It serves as a primary method for creating buildings, massive structures, and intricate sculptures. This craft involves working with stone as the main material, often using mortar to bind pieces together. Mortar is a paste used to join stones into walls or covers for structures. Stonemasonry is one of the oldest professions in human history. For thousands of years, it has been used to build temples, monuments, and entire cities.

The process of stonemasonry follows a specific sequence of specialized roles. First, a quarryman works at the extraction site. They cut or split large pieces of rock from the earth. These blocks are then moved away for further refinement. Next, a sawyer mason processes these blocks into dimension stone. This means cutting the stone into specific, required sizes using saws. Sawyer masons often use diamond-coated tools to handle the hard material. They may examine grain patterns to determine how the stone will cleave or split.

After the stone is sized, it moves to the workshop stage. Here, a banker mason specializes in shaping the stone for a building's design. They work from templates or bed moulds to ensure accuracy. Banker masons use both hand and power tools to carve details. They might create simple chamfers or complex architectural features like tracery windows. It is vital that they bed the stone in the correct orientation. This ensures the stone sits in the building exactly as it was formed on the ground.

Once the stones are crafted, they must be installed at the construction site. A fixer mason is responsible for this highly skilled task. They use lifting tackle to move the heavy, pre-prepared stones into place. To secure the pieces, they use traditional lime mortars and grouts. Modern masons might also use epoxy resins, mastics, or specialized cements for stone cladding. They may even use metal fixings, such as dowels or cramps, to ensure stability. This stage requires extreme precision to meet the necessary tolerances.

Beyond structural work, some masons focus on the artistic side of the craft. Carver masons are the artists of the stonemasonry world. They use their creative abilities to carve figures, animals, or abstract designs into the stone. This work turns functional masonry into fine sculpture. Meanwhile, memorial masons focus on a specific type of carving. They create gravestones and inscriptions to honor the deceased. Both roles require exceptional skill to transform raw stone into beautiful, lasting art.

Historically, builders have used several classical techniques to manage weight and space. Ashlar masonry uses carefully dressed or cut stones for a smooth finish. In contrast, rubble masonry uses irregular stones, often as infill for walls. One of the oldest methods is the trabeated system. This involves placing a lintel, or horizontal beam, across two stone posts. Another method is arch masonry, also called an arcuated system. This creates a void or opening beneath a stone span. Some structures use dry stone masonry, which relies on friction and compression without any mortar.

In the modern era, stonemasonry is reinventing itself through new technology. While stone was once replaced by steel and concrete, it is returning due to its benefits. Many stones are stronger in compression than concrete. Furthermore, stone production emits less carbon dioxide, making it more sustainable. Today, designers use digital stereotomy. This involves using computer-aided design (CAD) and digital machining to cut complex vaults and arches.

New methods like the trabeated stone exoskeleton allow stone to serve as a building's outer frame. Other techniques, such as stone veneer, use thin layers of stone to decorate structural walls. These innovations allow stone to work alongside modern materials like engineered wood.
