A hidden treasure trove that could be worth billions of dollars has been discovered in southern India.

Over 1000kg of gold coins, sacks full of diamonds, and thousands of rare necklaces were found by auditors during an inventory check at the Sree Padmanabha Swamy temple.

It is believed that Kerala's former royals had their immense riches sealed within the temple walls.

The recent discovery has made the temple the richest in the country.
