These ancient megalithic walls were earthquake-resistant by design 🏛️ Built with tight-fitting polygonal stones. Andesite stones precisely cut to fit together like Legos. No mortar yet thousands of years of survival. Ancient dry-stone construction techniques allowed structures to flex and shift with seismic forces.
Key facts verified:
- Megalithic walls used earthquake-resistant construction with precisely fitted stones rather than rigid mortar
- No mortar was used in original construction - allowing flexibility and survival over millennia
- Inca and other ancient builders mastered polygonal masonry and precise cuts for seismic stability
- Ancient dry-stone construction techniques remain superior for earthquake resistance compared to rigid mortar-based modern methods
