There are a slew of witch-trial-related sights and walking tours to choose from in Salem and no single option hits every note. Many are seasonal and play up horror over history. This year-round museum, in a building that used to be a church, provides an informative overview of the 1692 hysteria with a slightly dated presentation: A series of dioramas are populated with life-size human figures that light up in sequence as recorded narration, taken from historic documents, describes the pertinent events. The story is grim—most of those accused of “witchcraft” were executed by hanging, and one was pressed to death by stones piled on a board on his chest—but its anti-prejudice message is both clear and timeless.
