Well, now they've announced that they are making the biggest expansion ever to date. That means that as of 6 April 2019 you'll be able to visit Gringotts Wizarding Bank.
Gringotts Bank played a huge part in the wildly popular film and book series, featuring in the very first instalment as Harry discovered he is not only a wizard, but also loaded.
It also appears in the final book, when Harry, Ron Weasley, and Hermione Granger break into the bank and crash out through it riding on the back of a dragon.

Move over, Game of Thrones, J.K. Rowling got there first with regards to dragon-based destruction on the big screen.
Visitors to the new area of the tour - a must-see for Hogwarts-heads - will be greeted by the huge pillared hall of the bank that has been decorated with 'three magnificent crystal chandeliers and finished with real brass leaf'.
The press release continues: "Inkwells, quills, ledgers and piles of Galleons, Sickles and Knuts will complete the goblin tellers' desks as seen on screen."
On top of that, you'll be able to see some of the amazing prosthetics that turned actors like Warwick Davis - who played the goblin bank worker Griphook - into the sharp-toothed, black-eyed character that viewers of the films will remember.

There's more. Once through the main hall, visitors will be able to view the LeStrange vault - the vault that Harry and co scoured for horcruxes in Harry Potter and the Deathly Hallows - and have pictures taken within the bowels of the bank, surrounded by Bellatrix LeStrange and her family's hoard of treasure.
This addition which is - as mentioned - the biggest expansion to the tour since it opened in March 2012, was built by many of the original crew from the films, including Stuart Craig, who won a BAFTA and an Academy Award for his production design skills.
You can guarantee an authentic experience, then.

As part of this expansion, the tour will also now have a huge new lobby and café, serving food and drink inspired by the Wizarding World. Butterbeer on draught, you'd imagine.
This whole lot won't cost you any more than the general ticket price, either.
In that general admission price, you already get to see several other areas of Harry Potter history.
That means flinging open the doors to the Great Hall of Hogwarts, boarding the Hogwarts Express at Platform 9¾, visiting the office of Headmaster Albus Dumbledore, seeing the Forbidden Forest, and - of course - visiting the magical high street Diagon Alley.
Seriously, if Harry Potter is your thing, you'll have to get to this. Tickets can be purchased here.
