The Sionis Steel Mill.jpg

The Industrial District is a very large part of Old Gotham, and eventually, Arkham City. It consisted of the Joker's Base of operations, Zsasz's Hideout, and the building that Hugo Strange locked Nora Fries in. The Steel Mill was also where most of Batman: Arkham City took place.

There's also Victor Zsasz's Hideout, the place where Nora Fries was locked up by Hugo Strange, a Giant Ferris Wheel where Batman found Azrael, and a boat owned by Falcone Shipping that was flooded with Scarecrow's Fear Toxin and a dead Joker Henchman.
