Rikers Island is a large island located in the East River between the boroughs of Queens and Bronx in New York City. It is primarily known for housing the Rikers Island Jail Complex, which serves as a detention center for individuals awaiting trial or serving short sentences. The facility has been in operation since the 1930s and is one of the largest correctional institutions in the United States. The island covers approximately 400 acres and is accessible by bridge and ferry. It has faced significant scrutiny over the years due to concerns about conditions within the jail, including issues related to safety, overcrowding, and treatment of inmates. Efforts for reform and closure of the facility have been ongoing.
