A Lot of what you will see is the original tunnel clues from George Crowninshield’s Sr. home. The door probably led to the basement of the Bonded Warehouse. These pictures are under the building in the front.
They tended to leave the basements intact with the old tunnel connections when they built a new home on the property. When they built the Custom House Lord, McIntyres, Roberts, and Upham were involved. These were the guys who were building all of the homes in Salem that were attached to the tunnels. You can see the sealed entrance below the furnace, the arch supports you would see in tunnels and subways in the ceiling, and the fireplace arches with sealed stairs going down into the tunnels.
