It's been more than 20 years since fans were first introduced to the wonderful world of Hogwarts.

Harry Potter and the Philosopher's Stone was just the first step in a magical journey that has now spawned seven books; eight films; a stage adaptation and a spin-off series. The first book introduced us to the world of witchcraft and wizardry, Hogwarts - and, of course, The Boy Who Lived and He Who Must Not Be Named. After putting your knowledge of the first book to the test, we figured it was time to move on to the Chamber of Secrets.  It's time to take a stroll down memory lane and find out how well you really remember the Golden Trio's second year at Hogwarts. Good luck! And if you're looking to brush up. on your Harry Potter knowledge, we've got some good news. The Lighthouse Cinema in Dublin recently announced that they are going to be hosting a massive (and magical-sounding) Harry Potter sleepover, where they'll be screening all eight films. The almost-24-hour-long festivities kick off on Sunday, July 26 in the "ultimate marathon event" - and tickets went quicker than you could say Accio Popcorn! But it's not all bad news, as the cinema will also be screening the films every Sunday and Tuesday beginning on July 7. You can find out more information here.
