Mysterious Doors Around the World That No One Has Ever Opened
Some doors stay closed for good reason, or at least that’s what those guarding them believe. Around the world, sealed entrances remain untouched in temples, monuments, hotels, and historic sites. They’re blocked by politics, science, religion, and fear. What’s behind them ranges from national archives to rumored tombs and forgotten rooms. The mystery grows the longer the door stays closed.

Vault B is situated beneath Kerala’s famed temple, untouched even after India’s Supreme Court ordered the opening of nearby vaults in 2011.
