Today, I went to 9 3/4 line that used in a Harry Potter movie! It's located in a western hall of King's cross station and it's a shooting spot where many fans are gathered. You need to wait at least 1 hour when it gets crowded so I recommend you to go there in the morning! Also, outside of Cross Sint Pancrass alongside with King's Cross station was used in "Harry Potter and the Order of Phoenix". it's so huge that has a strong visual impact.

PLACE: King's Cross Staion
