Overview

• Researchers analyzed laser scans and diagrams to uncover the construction methods of the Menga dolmen.
• The structure's builders transported 150-ton stones from a quarry using wooden sleds and tracks.
• Stones were precisely placed at inward angles to enhance stability and create a trapezoidal shape.
• The capstones were carved to distribute stress, showcasing an early understanding of the arch principle.
• The dolmen has withstood seismic activity for 6,000 years due to its advanced engineering.
