The cache of valuables was discovered at the Sree Padmanabhaswamy temple in Thiruvananthapuram, in the south-west Indian state of Kerala.
Estimates suggest that the jewels uncovered in secret underground vaults could have a value of around 500billion rupees (approximately £7billion), which would make Sree Padmanabhaswamy one of the most valuable temples in India.
An inventory of the temple's goods is still being conducted by a seven-member panel appointed by the Supreme Court of India. Kerala Chief Secretary K. Jayakumar told the AFP news agency: 'We are yet to open one more secret chamber which has not been opened for nearly 140 years.'
Two chambers were opened up for the first time in over a century on June 30 and July 1, with discoveries including thousands of gold coins, jewels and one necklace that is around 18feet (6metres) long.
A trust established by descendants of the Travancore royal family, who had the temple constructed in the first place, had been in charge of the structure until recently. But India's supreme court recently ruled that administration of the temple should be turned over to the state in order to ensure that the valuables were protected.
