At first, I thought it was a story about the Hindu monkey god, Hanuman, whom I've used as an avatar for this blog.
It turns out, the lost city is not in India, but in the Central American jungles of Honduras. These ruins have not been looted or disturbed in centuries. So little is know about the mysterious culture which lived here, that it has not been named yet.
After legends about the city lingered since at least the 1920's, modern researchers launched a search for the "White City" of the monkey god. The site was discovered using lidar laser surveying, after a valley in the rain forest was identified as a possible location.
This shows how the use of technology & our accumulated knowledge has helped unlock our past in ways that were previously unimaginable.
