Iserlohn Fortress was an Imperial fortress located near the Tiamat Starzone. Existing within the eponymously named Iserlohn Corridor, one of only two navigable star routes between the Phezzan Corridor), Iserlohn kept the territories of the Galactic Empire safe from Alliance invasion.

The fortress had a diameter of 60 kilometres and a mass of nearly 60 trillion tonnes. Its primary weapon was an enormous X-ray beam cannon, the Thor Hammer, which was capable of destroying large numbers of enemy vessels in a single shot. Its docks could berth 20,000 ships, and its dedicated agriculture blocks could sustain both a garrison of up to 2 million and a civilian population of up to 3 million indefinitely. The fortress exterior was a several-layer-thick coating of liquid hydro-metal, which absorbed solid projectiles and reflected directed energy; hundreds of cannon turrets floated in this liquid and would rise to fire at approaching enemies.
