Shiganshina District (Before the Fall)

Shiganshina District (シガンシナ区) is a town located on the south edge of Wall Maria.

Story
Although it is common that Shinganshina District along Wall Maria fell in 845 when the Colossus Titan and Armored Titan destroy the gate, it actually attacked in 775 when Titan cultists open the gate and allow a Titan 'Mammon' and roam around, killing around 5000 people before the Survey Corps drove it out of Shingashina.

Despite the horrific events, the royal government managed to suppress the event information that not a mention of it in 845. It is either by the Founding Titan erasing memories or the Interior Military Police silencing the news.
