Las Noches was 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 room 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 was colored white.
Now all that remains of the palaces former glory are ruins buffered by the endless swirling sands and the countless battles there. The Ruins are home to most Hollows that claim themselves as King/ Queen of Hueco Mundo when really all they are is delusional remnants that cling to the old ways of when lords of Hueco Mundo like Barragan and Aizen once held. This area is now said to be even more dangerous now then Menos forest and is avoided by most Gillian Hollows and even some Adjuches Hollows. The Desert the surrounds it stands atop a main part of the Vast Menos Grande inhabited forest and even now trees of crystal hue poke out through the domed shell of the forest.
