That's a link to part 1/5 of the whole documentary. The others can easily be found on Youtube. If you've never heard of it, watch the documentary, It's definitely worth it.
For anyone who already knows, or has learned about it. What are your opinions? What do you think the treasure is? Why coconut fibers? A lot about this place is pretty interesting. I'd love to some day see it for myself.
What are your thoughts?
