Padmanabhaswamy Temple treasure, India, 2011
With its elaborate exterior, Padmanabhaswamy Temple is a decadent sight from the outside – yet this is just the tip of the iceberg. Buried deep within, in a series of vaults, lie treasures said to be worth billions of pounds.
The contents of one chamber, Vault A, remained shrouded in mystery for years, but after a legal battle it was finally unsealed in 2011 so an inventory could be taken.
