4. There is a Former Women’s Prison on West 20th Street
What was once the Bayview Correctional Facility sits on West 20th Street, a former women’s prison that was one of the only state penitentiaries found within the city. It has not been touched after it closed in 2012 due to $600,000 damages sustained during Superstorm Sandy. The fenced portion on the roof was once the facility’s recreation area.
