These pictures are scans of negatives that were not very carefully stored. I shot this roll of film on a cross country trip in 1993. These are the ruins of the Ensley Steel Works (TCI works) which were built by the Tennessee Coal, Iron and Railroad Company beginning in 1888. The mill was acquired by U.S. Steel in 1907 and operated until 1976. From what I can tell the condition of these ruins is still very similar their condition in 1993. Recent pictures and Google Earth indicate that all of the structures in these photos are still standing- the only difference being slightly more vegetation. The ruins were easy to get to from the Northwest side, via street parking near a school/day-care on Pleasant Hill Road. It was a really interesting place to walk around and I'd love to go back. More about the Ensley works on Birmingham Wiki.
Ensley was developed as a separate city when the steel works were built. It merged with Birmingham in 1910 and is now a neighborhood. It has it's own (mostly empty) downtown commercial district.
