Shiganshina District (Anime)

The Shiganshina District (シガンシナ区) is a town located on the south edge of Wall Maria; and is the hometown of Eren Jaeger, Armin Arlelt, and Mikasa Ackermann. The district is built within an outcrop of Wall Maria. Since Shiganshina is located to the south, Titans usually came to this district's Walls in an attempt to consume humans, but were only able to break through in the year 845 because of the 60-meter tall Colossal Titan.

The Fall of Shiganshina arc
In the year 845, the Colossal Titan breached Wall Maria and the front gate of Shiganshina by kicking a hole through it, allowing Titans to overrun the city. Shortly afterward, the Armored Titan broke down the back gate, fully breaching Wall Maria and forcing humanity to abandon Wall Maria and retreat behind Wall Rose. It is also the first city to be attacked by the Titans after a century of peace.

Eve of the Counterattack arc
There is little mention of Shiganshina after the attack. Erwin decides to appear at the recruitment ceremony of the 104th Cadet Corps to persuade them to join the Scout Regiment. Erwin mentions the basement in Eren's house, and how it can hold the answer to the mystery of the Titans. He also explains that by accessing his basement, they would need to find a way to reclaim Shiganshina and Wall Maria altogether. A month later, Erwin and the Scout Regiment set out on the 57th exterior mission as a practice run to Shiganshina.

Clash of the Titans arc
Reiner Braun, Bertholdt Hoover, and Ymir rest on top of the Wall in Shiganshina, after escaping the horde of Titans sent to attack them with the Coordinate. Ymir thanks, Reiner and Bertholdt for inadvertently rescuing her from her nightmare, by attacking the Walls, and promises to return with them to their Hometown.

The Beast Titan's operator is seen waiting on top of the inner gate of Shiganshina, having recently ejected from his Titan.
