6. One of the Houses Is Not a House At All

Joralemon Street-MTA Ventilator-Fake Townhouse Brownstone-Brooklyn Heights-NYC-001

The ‘house’ at 58 Joralemon Street is actually not a house at all, but rather the world’s only Greek-Revival subway ventilator. The structure also works as an emergency exit for the Lexington Avenue line (4/5) that runs there between the Borough Hall and Bowling Green stops. The facade of red brick and blacked out “windows” blends almost perfectly with the neighborhood’s aesthetic, or at least better than an industrial ventilator would.
