Pottermania is back! From its humble beginnings as an idea born on a train journey, and laid to paper in a small café in Edinburgh, the first book in the Harry Potter series sparked a global phenomenon. 20 years on, Harry Potter and the Philosopher's Stone has sold over 450 million copies worldwide, in 79 languages, inspired a major movie franchise, a spellbinding theatre production, and a number of thrilling sightseeing experiences.

Yesterday the British Library has launched a dedicated exhibition called Harry Potter: A History of Magic, and Evan Evans, London's largest sightseeing company, which specialises in city tours and out-of-town excursions, has launched a brand new specially-themed walking tour, Harry Potter Film Locations. So what better way to get your Hogwarts fix than enjoy a wizard-themed day out in London?!

The British Library's ticketed exhibition features rare books, manuscripts and magical objects, capturing the traditions of folklore and magic which are at the heart of the Harry Potter stories. Visitors can marvel at original drafts and drawings by J.K. Rowling and illustrator Jim Kay, both on display for the first time.

Evan Evans' half day tour transports Muggles into the magical world of Harry Potter as they discover the London locations that played starring roles in the film series and inspired the books. Stand in the footsteps of the world's most famous wizard at the entrance to the Ministry of Magic, stroll through the alleyways that inspired Diagon Alley and see the very spot where Death Eaters destroyed the Millennium Bridge. Visitors will then try their luck at getting onto the famous Platform 9¾ as the tour concludes. This two and a half hour morning tour is the perfect way for avid “Potterheads” to explore the capital.
