Ancient Building Techniques: Metal Staples in the Bricks of Ancient Civilizations
***
Recently, archaeologists have unearthed artifacts that demonstrate how various ancient civilizations, scattered throughout the world, used a technology that was advanced for the time: metal staples inserted between bricks to reinforce building structures. This technique, which might seem modern, was already in use thousands of years ago, revealing a level of engineering and knowledge of materials that was surprising for those times.ù

One of the best-known examples is that of Inca constructions in South America, where massive stone blocks were joined by metal staples, often made of copper or bronze. These staples, locally called “tumi”, not only held the blocks together, but also helped to distribute seismic forces, making the structures resistant to earthquakes. Similarly, in ancient Egypt, traces of metal staples have been found in the foundations of temples and pyramids, used to stabilize colossal stone blocks.

Also in Asia, particularly in Cambodia, the temples of Angkor Wat show evidence of the use of metal clamps to hold bricks together. These elements, often made of iron, were inserted with precision in the joints between the blocks, demonstrating an in-depth knowledge of the properties of the materials and of construction techniques. Curiously, civilizations so distant from one another, both geographically and culturally, seem to have developed similar solutions, perhaps in response to common structural requirements, such as the need to withstand seismic events or extreme weather.

The presence of these metal braces raises fascinating questions about the technological level achieved by these civilizations. It is possible that they had access to more advanced metallurgical knowledge than previously thought, or that they had developed metalworking techniques independently. Some scholars hypothesize that this knowledge could have been handed down from even more ancient civilizations, now lost, or that it is the result of cultural and technological exchanges between distant peoples.

These discoveries not only help us better understand the engineering skills of our ancestors, but also remind us how full of surprises the past is. Metal brackets in bricks are an example of how ancient civilizations, even without modern technologies, knew how to make the most of available resources to create structures that have stood the test of time. A legacy that continues to inspire and make us reflect on the level of knowledge humanity achieved thousands of years ago.
