Marvels of ancient engineering

THE GREAT PYRAMIDS OF GIZA 
Standing proudly on the sands of Egypt for over 4,500 years, the Great Pyramids of Giza are one of the most iconic symbols of human history. These incredible structures were built as tombs for the pharaohs and are a testament to the ingenuity, skill and determination of ancient Egyptian civilisation. How were these massive monuments constructed with such precision, and what secrets do they still hold?
The Engineering Wonder: The largest pyramid, the Great Pyramid of Khufu, originally stood at an astonishing height of 146 metres (now slightly shorter due to erosion). It was built using over 2 million limestone blocks, each weighing between 2 and 15 tons. Ancient engineers used ramps, levers and sheer manpower to move and position these massive stones. The pyramids were not just architectural achievements; they were also designed with astronomical precision. The Great Pyramid is aligned almost perfectly with the cardinal points of the compass and was constructed to reflect significant celestial events. This alignment demonstrates the Egyptians' advanced understanding of mathematics and astronomy.
The Purpose and Legacy: The pyramids served as monumental tombs to honour and protect the pharaohs in the afterlife. The chambers inside were filled with treasures, food and artifacts to support their journey beyonddeath. While many of these treasures were lost to grave robbers over the centuries, the pyramid themselves remain as enduring legacies of a civilisation that continues to fascinate and inspire. The Great Pyramids of Giza are more than just ancient tombs – they are monuments to human ambition, skill and the desire to reach for the stars. Despite centuries of study, these architectural wonders continue to hold secrets that spark curiosity and awe. They remind us of the incredible achievements of those who came before us and the mysteries that still lie waiting to be unravelled. The Great Pyramid’s base is so precisely aligned that its error margin is less than 0.05%. Contrary to popular belief, many pyramid builders were not slaves but skilled labourers who were well-fed and respected for their work.
Hidden Chambers: Researchers have recently discovered a mysterious void inside the Great Pyramid using advanced scanning technology, but its purpose remains unknown.
The Wet Sand Theory: This theory builds on ancient depictions and modern experiments showing that wetting the sand in front of sledges reduces friction, making it easier to transport heavy stones. Workers might have used water to harden the sand, allowing them to drag massive stones across desert terrain with less effort.
Internal Spiral Ramps: Proposed by French architect Jean-Pierre Houdin, this theory suggests the pyramids were built using internal spiral ramps rather than external ones. The internal ramps, hidden within the structure, would have been used to move stones up to higher levels.
