[00:00:00]Beneath the African sky, the great enclosure of Great Zimbabwe stands as an architectural wonder.

[00:00:07]Massive granite walls rise without a drop of mortar, relying solely on sophisticated drystone engineering.

[00:00:31]Curved geometries and sloped walls dissipate seismic energy, preventing collapse during earthquakes.

[00:00:39]Modern mapping reveals a hidden language of precision-cut joints and a lost structural intelligence.
