Fans of the fantasy series can tour the likes of The Great Hall at Oxford's Christ Church College - where the famous dining scenes at Hogwarts are held - or The Bodleian Library, also in Oxford, which was used as the Hogwarts Infirmary in the first movie, 'Harry Potter and The Philosopher's Stone'.
Christ Church's The Great Hall is full of "Renaissance splendour" and is still used for mealtimes every day. Members of the college may dine here three times a day but if they come for evening dinner, they must adhere to a strict dress code of formal gowns.
Elsewhere, you can use Google's Street View to visit the likes of London's Leadenhall Market - which was where The Leaky Cauldron was situated - as well as the Millennium Bridge, which was where the scene of the dementor attack was filmed.
Glenfinnan Viaduct is also a popular place to virtually visit as it is the home of the famous Hogwarts Express train route.
J.K. Rowling recently unveiled a set of 'Harry Potter' themed word searches, quizzes, crosswords among other activities.
It explains on the site: "You'll find all the latest things to keep you occupied - from special activity kits from Bloomsbury to Scholastic, to nifty magical craft videos (teach your friends how to draw a Niffler!) fun articles, quizzes, puzzles and more. We're casting a Banishing Charm on boredom."
