King's Cross Railway station is a major London railway that was opened in 1852. King's Cross is featured in the Harry Potter series by J.K. Rowling. The Hogwarts Express uses a secret platform, 9 3/4, to transport students to Hogwarts. King's Cross has since placed a cast iron 9 3/4 sign on the wall against where the movie was filmed with part of a luggage trolley under the sign.
You can't go to London without stopping by the iconic platform 9 3/4 at Kings Cross station, where the bespectacled 11-year-old boy from the Harry Potter books and movies made his first attempt to cross from the Muggle world into the wizarding one waiting for him. The station recently added a Platform 9 3/4 shop next to its trolley, so fans can shop for Hogwarts gear before imagining their trip through the brick wall.
