Trivia, insights & behind the scenes
The term 'rediscovered' in the title is contested—Cambodians maintained continuous knowledge of Angkor Wat as a sacred site, while Western archaeology prioritized monument preservation over living religious practice.
The lidar technology shown was partly funded by a reality TV show that never aired, because the 'pristine jungle' they expected had already been partially logged.
