There are a lot of Harry Potter locations in Edinburgh and in Scotland in general but in London you can visit the studio where the majority of the Harry Potter films were shot and a lot of Harry Potter filming locations. Every Harry Potter movie has scenes that were filmed in London. Locations range from Leadenhall Market (the entrance to Diagon Alley) through to Kings Cross Station (home of platform 9 3/4 and boarding point of the Hogwarts Express).
In the heart of Regent’s Park, a little way north of central London, is London Zoo – the world’s oldest scientific zoo. It was in the Reptile House at London Zoo that Harry sets a Burmese python free in Harry Potter and the Philosopher’s Stone. This scene was filmed on location in the Reptile House.
Remember when Harry Potter takes the awesome triple decker night bus in Harry Potter and the Prisoner of Azkaban? The Knight Bus squeezes itself between two standard double decker buses. And this scene takes place on Lambeth Bridge, which is the bridge upstream from Westminster Bridge.
In the Victorian Leadenhall Market there is the entrance to the Leaky Cauldron. More specifically, the door to an opticians shop in Bulls Head passage was used as the Leaky Cauldron entrance. After his ride on the Knight Bus, Harry disembarks in Borough Market at what is in real life the “Chez Michele” flower shop.
In the movie Harry Potter and the Half Blood Prince, Harry and Mr Weasley enter a phone box which serves as the entrance to the Ministry of Magic. The location is the intersection of Scotland Place and New Scotland Yard.
You can take a look at the building that was used for Gringotts – the grand Australia House, which sits on the Strand and was where the interior scenes of Gringotts were filmed.
In Harry Potter and the Order of the Phoenix, Harry and Mr. Weasley travel through Westminster tube station necessitating it being closed for the full day.
Platform 9 and 3/4 where the train to Hogwarts leaves is at Kings Cross station.
In Harry Potter and the Deathly Hallows Part 1, Piccadilly Circus was a key location in the film when Ron, Hermione, and Harry narrowly avoided being hit by a London bus.
Last on my list of Harry Potter filming locations in London is the Warner Bros Studio . This is actually a little way outside the city, near Watford Junction, but it’s a fabulous place to visit!
