Standing over the town of Bethlehem, PA like some kind of postmodern Oz is the once-mighty Bethlehem Steel mill. From a distance it appears almost majestic, towering over every other structure in the town and challenging the surrounding mountains themselves for supremacy.

On closer inspection though, we find a shell of what was at one time the major economic force in this small mountain town. The byzantine array of pipes and scaffolding are nothing more than a curiosity now, but from 1857 until 2003 Bethlehem Steel was the second leading producer of steel in the U.S. and one of the foremost shipbuilding companies in the world.

Now only the ghost of the mill itself remains, a memorial to a fallen giant bankrupted in 2001, and gone completely by 2005. The "interior" shots in this gallery aren't actually interior shots at all. So little of the structure remains that it wasn't necessary to be inside to get them.

I can't help but think of the citizens on the other side of the railway that suddenly found themselves without a livelihood when the Bethlehem plant shut down. In one photo you see the remains of a wall that bears a stirking resemblance to the aqueducts of ancient Rome. There's a funny sort of parallel in that.
