Under Boston · STOP 04 · Downtown
The subway builders listed this graveyard as one of seven places the first subway breathed.
In one of Boston's oldest graveyards, beside King's Chapel on Tremont Street, one structure among the slate headstones isn't a grave. It's been breathing for the subway since the 1890s, when the builders listed this yard as one of seven places the tunnel was ventilated. You can see it from the sidewalk, through the fence.
This is stop 4 of Under Boston. Walk it - any two stops are free.
