While Manhattan's streets were largely laid out with the Commissioners' Plan of 1811, this grid system was only implemented between Houston and 155th Streets. The plan left Greenwich Village with its long-established mews, alleys, and courts, many of which date to the city's early colonial period, intact. While not exclusively in the Village, most of the secret streets on this list are located there among the organically developed 18th-century street plan. While some changes have come to these streetscapes in the last century, in most cases their concealment and a healthy dose of historic preservation work have aided in their continued survival in the 21st century.

"When Prohibition was introduced, I hoped that it would be widely supported by public opinion... I have slowly and reluctantly come to believe that this has not been the result. Instead, drinking has generally increased; the speakeasy has replaced the saloon; a vast army of lawbreakers has appeared; many of our best citizens have openly ignored Prohibition." –– John D. Rockefeller

"Extra Place, north from East 1st Street, showing at the extremity of this blind alley, buildings that face on the south side of East 2nd Street, under demolition, 1938." One of the doors seen on the left of this photograph would go on to become the back door to the famed punk club CBGB's. In 1976 the Ramones shot the cover for their album, Rocket to Russia, on Extra Place, likely against the brick wall seen in this photograph.
