In this episode, Lucas and Luna explore Zhou Daguan's descriptions of the...

While the Khmer Empire is famous for its stone temples and elaborate waterworks, a quieter but equally transformative technology shaped its rise and fall: iron.

Deep inside Angkor Wat's third gallery, a set of inscriptions carved in 1546 tells a story the empire's builders never imagined.

For decades, historians have pointed to climate change, water mismanagement, and military pressure from Ayutthaya as the main culprits in Angkor's collapse.

This episode explores the surprising role of tree roots, specifically the silk-cotton and strangler fig trees, in both destroying and preserving Angkor's stone temples. Lucas and Luna discuss how the famous Ta Prohm temple, deliberately left unrestored, sho...
