The Hole-in-the-Wall was a popular saloon and underworld hangout in what is now the South Street Seaport, Manhattan, New York City during the early- to mid-19th century.

[1] It was one of many dive bars and similar establishments in New York's infamous Fourth Ward, located at the corner of Water and Dover Streets.

The saloon was owned by "One Armed" Charley Monell and featured notorious female criminals Kate Flannery and Gallus Mag as bouncers.

[2] Both women were employed by Monell as lieutenants in his local criminal organization, which included shanghaiing,[3] and the latter woman supposedly kept a collection of human ears which she had bitten off from unruly customers in bar brawls.

Sadie the Goat, the later leader of the Charlton Street Gang, was of the many victims who lost her ear in a brawl with Gallus Mag.
