Three of the places these walks talk about are still there and cost nothing to stand in. The Salem Witch Trials Memorial, off Charter Street, opened on 5 August 1992 — twenty stone benches, one for each person executed, with their words cut into the threshold. It is free and open from dawn to dusk, and in October the city asks visitors to reserve a free slot.
Proctor’s Ledge is the execution site itself. Sidney Perley worked out where it was in 1921, a university team confirmed it in January 2016, and the city dedicated the small memorial there on 19 July 2017. It is free, it is a short walk from the centre, and it has no parking of its own — which is the practical thing nobody tells you.
The Witch House on Essex Street is the only building still standing with a direct connection to the trials: it was the home of Jonathan Corwin, one of the judges. That one is not free — tickets start at $17 and the hours change by season. None of the eight walks above includes entry to it, so if you want to go inside, that is a separate ticket and a separate hour.
