Las Noches is a massive fortress which can be seen for miles It consists of a main building with a domed center surrounded by several large towers and smaller buildings. Atop the dome are five smaller towers, which appear to contain areas such as Aizen's throne rooms and the Espada meeting hall. In the room where Orihime Inoue is kept, there is one large Middle-Eastern rug on the ground that is facing outside, much like those in rooms used for Islamic prayer. Like everything else in Hueco Mundo, the main building is colored white. Las Noches is easily the largest structure in the Bleach universe, appearing as large as (if not larger than) Seireitei in Soul Society.
