Vault 713

In Harry Potter and the Philosipher's Stone, Harry's first trip to Gringotts with Hagrid took him to Vault 713. Vault 713 was a high-security vault, if anyone but a Gringotts goblin tried to break into it they would be sucked in. When Harry asked how often they check if someone is inside, Griphook replies "Around ever ten years."

Vault 713 housed the Philosipher's Stone. It is unknown if that vault was used again after the Stone was taken out.
