Wall Rose is the second outermost Wall following Wall Maria. It was breached by the Colossus Titan 5 years after the fall of Wall Maria, but the breach was later sealed by Eren Jaeger with assistance from the military. It was thought to have been breached again after Titans appeared inside it a little over a month later.[5]
