Cyclopean walls were built during the Bronze Age Mycenaean civilization—stones were roughly shaped and tightly interlocked without mortar, creating earthquake-resistant polygonal masonry that survives while other structures crumble. Scholars debate their purpose: gates are sparse and walls sometimes descend downhill, leading some to argue defense wasn't the sole goal, with privacy and elite display proposed as additional motivations.
Cyclopean walls built without metal tools; purpose was privacy and display, not defense

Key facts
- Cyclopean walls were built before iron/bronze age without metal tools; stones were slowly polished into shape
- Each stone had to be fully finished before the next one could be placed, preventing parallel work
- Polygonal masonry is earthquake and water resistant, explaining why walls survive when other structures do not
- Walls were NOT built for military defense: gates are missing, walls go downhill giving advantage to invaders, towers were added later
- Speaker argues the purpose was 'privacy and showoff' - elite separation from populace while displaying wealth
- Examples cited from Cosa, Segni, Norba, Orbetello in Italy, Kusco in Peru, and Japan all show similar non-military characteristics
