Breaking through the fourth wall with terrifying visions to send tingles up even the sturdiest spines, the Witches Cottage live witchcraft and ghost show interacts with audience members for a chilling introduction to Salem’s supernatural side. Guests begin their journey in the theater’s lobby, mystically transformed into an old witch’s cottage complete with bubbling cauldron, pictorial remnants of the witchcraft trials of 1692, and a utility closet full of retired brooms. Guests will feel around in the foggy 75-seat theater for their seats and gasp in horror as a shadowy wendigo spirit slinks toward the audience. Rekindle entrepreneurial ambitions of opening a soul pawn shop as you witness a puritan entering into a dark pact with the devil, and then retire said dreams as you meet, face-to-face, the soulless entities of the underworld’s darkest corners. Throughout the show, Salem history and legend weave truth and myth into ghostly tales, blurring the lines of reality as if they were mere suggestions. The spooky performance ups its terror quotient during evening shows, with special nighttime events scattered throughout the week.
