"....The Whomping Willow is a very valuable, very violent tree planted alone in the middle of the school grounds. It was planted the same year that Lupin arrived at Hogwarts to disguise the opening to a secret passage from Hogwarts to the Shrieking Shack. Lupin would go through a hole in the Willow's roots every month to transform into a werewolf in the Shack where he couldn't hurt anyone. The Willow was so dangerous that it kept other people from entering the passage and encountering the werewolf..." - Potter.
