The Shrieking Shack
Hogsmeade Village is home to what’s known as the “most haunted house in Britain”. Many witches and wizards are thrilled at the sounds of the shack, but may fear that the curses inside are to dangerous to go anywhere near. The Shrieking Shack was used by Lupin during his Hogwarts years as a place to transform into a werewolf without endangering other students. There is one open passage into the Shrieking Shack, and that’s through the gap between the Whomping Willow’s roots.
The Whomping Willow, an attack tree, was planted in the time of Lupin’s school years to ensure the privacy of Lupin so he did not endanger other students while he was transformed. The only way to get past the Whomping Willow’s fighting branches is to press a knot by the gap in which the tunnel is located. Lupin’s best friends were Animagi’s, therefore could turn into animals. Sirius a dog, James a stag, and Pettigrew a rat. Pettigrew would turn into a rat and press the knob and all four would venture forth through the winding passages that led towards Hogsmeade into the Shrieking Shacks main room.
Inside the Shrieking Shack
Down through the shadowy hallway and through its twisting passageway, you eventually wind up at the end. After climbing up out of the hole, you are inside the deserted, boarded up, and torn up furniture main room of the Shrieking Shack itself. Everything within the Shrieking Shack is torn to bits by Lupin’s werewolf transformations. If you go through the hall and up the crumbling staircase, you’ll find yourself in the room in which Sirius had dragged Ron into to lure Harry so he could have a talk with him and confess the truth, and not the lies that everyone had staged up. Everything in this room is covered with dust and mixed debris. Through another doorway you will find a four-poster bed with dusty hangings.
