Photos of New York City’s Most Dangerous Neighborhood
“Bandit’s Roost,” pictured above, was once considered the most dangerous part in all of New York City.
Jacob A. Riis was a police reporter in 1877 and decided to document the people living in New York’s East Side slum district. His book, How the Other Half Lives: Studies Among the Tenements of New York, was the result of these photographs and was published in 1890.
