Cell block 14 at Eastern State Penitentiary. This particular cell block was built in 1926 and was the second ESP's three story cell blocks. Construction was done primarily using prison labor. Light streams down from the third floor skylights through a series of grates in the ceilings and floors illuminating the floors below. The prison is located on Fairmont Avenue in Philadelphia Pennsylvania and was built in 1829 and closed in 1971 remaining abandoned for several decades before being re-opened to the public as a history museum. A great, tripod friendly, place to spend a full day of photography.
