Harry Potter and the Philosopher’s Stone filmed on location at Alnwick Castle in autumn 2000.
The following year, Harry Potter and the Chamber of Secrets (the second film in the series) used Alnwick Castle for shooting.
The Outer Bailey is recognisable as the area where Harry and his fellow students learned to fly broomsticks with Madam Hooch (Zoe Wanamaker). Harry also learned the rules of wizarding sport Quidditch in the Outer Bailey.
The courtyards and baileys of Alnwick Castle were used to film Hogwarts students and staff going about their daily activities. Harry and Ron crash-landed the Weasley family’s flying car in the Inner Bailey.
The Lion Arch was a way in and out of Hogwarts, heading towards Hagrid’s cabin and the Forbidden Forest.
