Was looking at some satellite maps on Google last night and came across this in Chicago. Its a factory or probably an out building for the steel mill nearby. Where the arrow is pointing looked like a familar structure. Zooming in, I found a roundhouse complete with bridge still intact. But there is no tracks going to it, no escape tracks.
Looks to me like the roundhouse was incorparated into this building after some time.
Does anybody know anything about this? Whats the history. Why did the keep the roundhouse intact, and build a building around it?
Since I couldn't figure out how to capture the image, I had to take a picture of my monitor.
