Why Did Old Mansions Have a Secret Tunnel Under Them?

Did a tunnel beneath a mansion help its owners escape, or did it move coal while guests admired the rooms upstairs? Both kinds of route existed, but their dates and destinations tell very different stories. Martin examines a documented Cold War escape tunnel beneath the Marsh-Billings-Rockefeller Mansion, a coal delivery tunnel at The Elms, and an English estate tunnel built to screen coal traffic from view. He also tests an Oklahoma mansion's famous escape-tunnel story against the owner's records and explains why a concealed passage does not, by itself, prove a story about the Underground Railroad. Do not enter an unknown tunnel, hatch, or confined basement space. Ask the property owner or site manager what is known and use qualified professionals to assess a feature in your own building.
