Walls

The Walls are three large structures that mankind retreated behind after the Titans appeared. They are named after three goddesses; Maria (the outermost wall), Rose (the middle wall), and Sina (the innermost wall).

Description

The Walls reach about 50 meters in height from bottom to top and are incredibly strong in substance. They are too long to be guarded in their entirety. The tops of the Walls are lined with cannons mounted on rails which can fire on approaching Titans; however, they are not particularly effective due to the Titan's regeneration abilities.

To account for this, each Wall has four towns on their periphery known as "districts." As Titans are drawn towards large concentrations of people, humanity can focus its defences on these districts and repel the Titans more effectively. The districts are considered the worst places to live as they are at greater risk of a Titan invasion.

Titans primarily target the southern region, even before the loss of Wall Maria. As such, they are considered the most dangerous and least desirable places to live in. The northern districts are considered the most desirable regions, due to minimal Titan activity. However, the weather is brutally cold and makes the life for residents very difficult. Within each wall, there are other villages and towns. Dauper and Rakago are two examples of such villages.

In 845, it is breached by the Colossus Titan and Armored Titan and its territory is lost to the Titans.
