Padmanabhaswamy Temple is located in Thiruvananthapuram, there are 7 big basements under the Mangip Ray sanctum, which have big doors, on opening 6 doors, diamonds, precious stones and metal idols and thrones worth crores of rupees were found. However, the door of the 7th basement was not opened.

The 7th door itself is considered mysterious. There is no lock of any kind on this door. Just a snake shaped symbol is made. In fact, if beliefs are to be believed, if the seventh door of Padmanabhaswamy temple is opened, then many untoward incidents can happen.
