Every LEGO Hogwarts has to decide what to leave out. Mini Hogwarts Castle (40975) gets 6.5 inches, total, and somehow still finds room for the Great Hall, the Main Tower, the East Wing, and the Astronomy Tower. Then it goes further – lift the East Wing and the Chamber of Secrets is sitting underneath. LEGO built basements into a model roughly the size of a coffee mug. Mini Hogwarts Castle launches August 29 for $39.99, and it is not launching alone.
