👉 The oldest engineering in the world is the construction of the Great Pyramid of Giza, built around 2560 BC in Egypt. This monumental structure showcases early engineering principles, primarily in its massive stone masonry and precise alignment with astronomical bodies. The pyramid's base is a near-perfect square, and its sides are aligned almost perfectly with the four cardinal points (north, south, east, west). The ancient Egyptians used simple yet effective tools like copper chisels and wooden levers to move and place the enormous limestone blocks, some weighing several tons. The precision in its construction, including the internal chambers and passageways, reflects an advanced understanding of geometry and structural engineering for its time, predating modern engineering by millennia.
