Shiganshina District

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 Yeager, Armin Arlert, and Mikasa Ackerman. The district is built within an outcrop of Wall Maria. Since Shiganshina is located to the south, Titans usually come to the walls in an attempt to break through, but they haven't been successful until the year 845.

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 afterwards, 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.

The Female Titan arc
There is little mention of Shiganshina after the attack. Erwin decides to appear at the recruitment ceremony of the 104th Trainees Squad to persuade them to join the Survey Corps. 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 Survey Corps set out on the 57th Expedition as a practice run to Shiganshina.
