Wall Maria

Wall Maria is the outermost Wall of the human kingdom. Like the other Walls, Wall Maria is approximately 50 meters in height. The distance between Wall Maria and Wall Rose is around 100 km. Five years ago, it was breached by the Colossal Titan and Armored Titan, after about 100 years of peace and prosperity, and was lost to the Titans.[16] Several decades earlier a group of Titan worshippers opened the gates and let a Titan in.
