At some unknown point in the past, the Royal Government ordered the construction of an underground city below this district and others within Wall Sheena, but the plan was abandoned during construction leaving unused tunnels below the city.
The Stohess District is the prime location of the destruction caused by Annie Leonhart in her Titan Form, after Eren Yeager, Armin Arlert, Mikasa Ackerman and the Survey Corps expose her true identity. When a convoy takes Jean Kirstein (who is disguised as Eren) to the Imperial Capital for judgment, this is but a ploy against Annie to expose her. After a fight between her and Eren, she is ultimately captured, but causes considerable damage to the District, including opening up a crack in the Wall, revealing the Titan inside it. Erwin Smith takes full responsibility for the destruction of the District.
In the anime adaptation of Chapter 61, Anka says that the Colossus and Armored Titans broke the gates of Karanes District, instead of those of Stohess as it was originally in the manga. This seems to be a correction as Stohess is located in Wall Sheena, which would imply that both Wall Rose and Wall Sheena had fallen if this had been indeed the district attacked by the Titans.
