I just "discovered" this totally insane temple in India ! Read the "vault B" and "temple assets" sections on this wikipedia page :
https://en.wikipedia.org/wiki/Padmanabhaswamy_Temple
This temple contains several secret chambers (or "vaults") that hide an extremelly LARGE treasure of gold and jewels, Frank Herbert's Dune style ! The treasure accumulated since several thousands of years.
The India governement openend several of the vaults in 2011 and 2014 for inventory. The known treasure that was discovered at that time has a value estimated at several dozens of BILLIONS of US$ ! (conservative estimation).
The vault B, which is by far the largest one, has never been opened yet, for religious and superstition reasons (fear of a major catastrophy and destruction !). There are large deaons and snakes carved on the only ver large door (fuck this is real Quake we are talking here !).
There are lots of videos on YouTube showing the vault B door. See this one :
