Walking tour. Just east of today’s City Hall and Municipal Building, this was once was a foul-smelling, disease-ridden district. Brought to life in the movie Gangs of New York, it was a place of violence, gang wars, poverty, and corruption. The district evokes such places of notoriety as Paradise Square, Cow Bay, and Bottle Alley, and such gangs as the Roach Guards, Plug Uglies, Shirt Tails, and Dead Rabbits.
