In 1692, the Salem jail was located on Prison Lane, today known as St. Peter Street. The building, at the corner of Prison Lane and County Street (present-day Federal Street) measured “thirteen feet stud, and twenty feet square, accommodated with a yard” when built as the county jail in 1684. It is thought to have had two stories. It was one of four jails where the majority of the accused witches were held (the others were in Boston, Cambridge, and Ipswich).
