Hogwarts School of Witchcraft and Wizardry is a fictional school created by J.K. Rowling for her Harry Potter series.
While the school's appearance was inspired by real places (like Alnwick Castle and Durham Cathedral in the UK), there isn't a real-life Hogwarts with magical classes and moving staircases.
However, many places around the world have been used as filming locations for the Harry Potter movies, which you can visit if you're a fan!
