FAQs About Cambodia Documentaries
Q: Was Angkor Wat actually “lost”?
A: Not really. Local Khmer people always knew the temples were there, and monks lived in them for centuries. It was only “lost” to the Western world until explorers “found” it again in the 1800s.
Q: What is LIDAR?
A: It stands for Light Detection and Ranging. It’s a laser that can see through the thick jungle leaves to map the ground underneath. It is the reason we now know Angkor was the largest city in the world 800 years ago.
Q: Which one should I watch first?
A: If you plan to visit Angkor Wat, you can watch a documentary on YouTube. If you love history, watch The Killing Fields. If you love adventure and temples, watch Jungle Atlantis. If you love music, watch Don’t Think I’ve Forgotten.
