Anyone who is curious about the deepest secrets and mysteries of the Catholic Church might be interested in the secret archives at the Vatican, which date back to the 8th century.

North Sentinel Island, India
This small archipelago located just off the Bay of Bengal in India is closed off to visitors. The local indigenous population are simply not interested in any outsiders of any kind. They have held on to their ways of living and this voluntary isolation means that they are not living a modern life, which is totally fine with them. Any vessels that approach the island are attacked by the Sentinelese and are not afraid to kill any intruders.
