Many of the world’s oldest structures still in existence have at least one thing in common – they are mostly made from some variation of stone. Masons have been harnessing the strength of this material for millenia, constructing beautiful and durable buildings, monuments, and infrastructure using their unique knowledge and skills.

When you look at iconic structures such as the Egyptian Pyramids, the Colosseum in Rome, the Taj Mahal in India, and the Great Wall of China that were first constructed thousands of years ago, you probably can’t help but wonder how they are possibly still standing strong after all this time.

Their impressive sturdiness is thanks to masonry, which combines the durability of some of nature’s toughest materials and the talents of skilled artisans to create some of the world’s longest-lasting structures.

History of Masonry

Thousands of years ago, as humans began settling into more permanent man-made shelters, they experimented with ways to build residences that were as protective and durable as the rare natural caves they sometimes lived in. Naturally, they first turned to using stone, strategically assembling piles into huts and developing some of the earliest stone masonry techniques. Soonthereafter, they started using clay mixed with straw and grass to create uniformly-shaped bricks that were initially baked in the sun, but eventually shifted to being fired in kilns to improve durability.

As building techniques continued to evolve, the art of masonry experienced a significant development with the invention of concrete by the Romans. By mixing cement made out of volcanic ash with water, lime, and stone fragments, they created a material that was faster and cheaper to make, and provided more flexibility in shapes, such as arches. Ever since, masonry has remained a valuable method of construction, as it offers unique aesthetic appeal with its colors, textures, and patterns, and also functional benefits such as sound control, fire resistance, and temperature regulation.

The Role of Masons

Masonry is generally considered to be the art of building different types of structures such as walls, sidewalks, and chimneys using brick, concrete, stone, or other similar materials. It is a skilled trade that requires knowledge of how to use proper tools and techniques to effectively arrange and bind pieces together for secure assembly.
