Hidden Passage Tied to Underground Railroad Found at Manhattan’s Merchant’s House Museum

Archaeologists say a concealed 2-by-2-foot shaft below a built-in drawer likely sheltered people escaping slavery, prompting the museum to revise how the site is interpreted.

Overview

  • Inspectors uncovered a rectangular cut beneath a heavy lower drawer in a second-floor built-in dresser, revealing a tight vertical space with a ladder to the ground floor.
  • Historians describe the feature as deliberate concealment designed to be undetectable to slave catchers and city marshals operating under laws like the 1850 Fugitive Slave Act.
  • The house was built in 1832 by Joseph Brewster, identified by experts as an abolitionist, and sold to the Tredwell family in 1835, though it remains unclear when the passage was made or who used it.
  • Preservation specialists, including Pratt Institute’s Michael Hiller, hailed the discovery as a generational find and urged formal protection of the concealed space.
  • The museum plans to fold the find into public interpretation and expand access, as the widely shared report—first detailed by NY1—spurs further research into the passage’s origins.
