Inspectors unearthing priceless treasures from a South Indian temple have had to halt their search because the final vault cannot be opened.
Five vaults replete with precious stones, gold and silver have already been opened in Kerala state’s Sree Padmanabhaswamy temple.
The haul’s value is now thought to have risen from 25 billion rupees ($500m) to 900 billion rupees ($20.3bn).
Historians say assessing the treasure’s true value will be very difficult.
The goods have not been officially valued and inspectors are merely taking an inventory.
The inspectors managed to open the outer doors of the sixth vault but found an iron wall inside it. The vault was last opened 136 years ago, according to temple records. Read more.
