Would be important to tell the informations that is said in Hogwarts Through the Centuries? Is there any important or undisclosed information about the series? Andre G. Dias (talk) 06:36, February 5, 2014 (Brazil)

There actually is no information said in this lecture, because it is never actually seen -- it's merely mentioned, at The Wizarding World of Harry Potter, as the reason why Muggles (the real-life park-goers) are being invited into Hogwarts and Hogsmeade (the theme park itself). --  Seth Cooper  owl post! 17:53, February 5, 2014 (UTC)
