Fans of Harry Potter will be familiar with the importance of Platform 9 ¾. The fictional platform is located at the very real King's Cross train station in London between platforms 9 and 10. In the Harry Potter books and films, Platform 9 ¾ is where the Hogwarts Express can be boarded on September 1 at 11am. There is a wrought iron archway in between platforms 9 and 10, and the students must walk or run directly at what appears to be a solid wall barrier.
Due to the logistics of platforms 9 and 10, filming of Platform 9 ¾ actually took place between platforms 4 and 5. But so many people came to see Platform 9 ¾ that eventually half of a luggage cart was permanently installed to look like it is going through the archway. Harry Potter fans from around the world come here to have their picture taken with the luggage cart. There is also a Harry Potter themed shop located nearby where you can purchase a wide variety of souvenirs and prop replicas.
Platform 9 ¾ is located in King's Cross train station in London. King's Cross is located along Euston Road next to St. Pancras International train station.
