Located on Essex Street, about one half block west of its intersection with Hawthorne Boulevard.
The Essex Institute houses the bulk of the original documents pertaining to the accusations, examinations, trials, and executions of the witches. The collection also contains other mementoes of the hysteria, most notably the walking canes used by the arthritic George Jacobs, Sr. who was executed for witchcraft. The afflicted girls asserted that Jacobs' specter beat them with these canes. The Institute is open to the public. There is an admission charge.
The former Essex Institute is now part of the Peabody Essex Museum. This building, Plummer Hall, is the museum library and the above-mentioned collection has been relocated to another area of the museum.
