6,000-Year-Old Spanish Megalith Reveals Advanced Neolithic Engineering

The Menga dolmen, predating Stonehenge by a millennium, demonstrates early mastery of physics, geometry, and geology.

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.
