The Harry Potter studio tour in London have announced their biggest addition yet and it sounds magical

Warner Bros.' Harry Potter tour has announced their "biggest expansion to date" - and it sounds absolutely magical.

The London-based home of all things related to J.K. Rowling's world of witchcraft and wizardry will be throwing open the doors to a Diagon Alley staple in April. Yes, that's right: Gringotts Wizarding Bank will officially open on April 6. Harry Potter fans will be able to walk through the towering marble pillars and into the grand banking hall, "decorated with three magnificent crystal chandeliers and finished with real brass leaf. Inkwells, quills, ledgers and piles of Galleons, Sickles and Knuts."

Then, once through the banking hall, fans will be able to explore the Lestrange Vault, where Bellatrix Lestrange stashed many of her treasures - including the Sword of Gryffindor and Helga Hufflepuff’s Cup, one of Voldemort’s many Horcruxes. The film series created 38,000 pieces of rubber treasure for the vault, including 7,014 Hufflepuff Cups. Guests will have the chance to step inside the Lestrange Vault and "surround themselves with treasure" to get that perfect souvenir snap. The 16,500 sqft addition as been built by many crew members who were a part of the Harry Potter film series, and entrance is included in the general admission price for a ticket.
