Symbolism, Imagery, Allegory
Well, this is where it all started… and this is where it all ends. Throughout the seven books of Rowling's series, Hogwarts has remained a kind of beacon of everything that's good about the wizarding world – a love of learning, adventure, and good companionship. The young witches and wizards enrolled there learn about more than just charms and hexes, if we're to take Harry, Ron, and Hermione as examples; like any good school, Hogwarts also teaches its students how to care for each other, and for the world around them. It's fitting, then, that the last battle of the wizarding war should take place in this space of learning – between Voldemort's small-minded and prejudiced forces of destruction and the hopeful, diverse citizens of the magical world, united at last by Harry.
