Platform 9 3/4 – King's Cross Station, Euston Rd, London N1 9AL, UK

As noted by Atlas Obscura, Platform 9 ¾ is a critical part of the “Harry Potter” story. As King’s Cross Station starred in many of the films, they have paid tribute to the fictional platform with a plaque and a luggage trolley embedded in the wall. The platform has been in several locations in the station but now has a permanent spot, close to platforms 9 and 10 under the walkway into the building. Right next door is a book store with a display of Harry Potter books in the window.
