It is known in Norse mythology as the great hall. It was governed by the King of the Norse gods, Odin.
It is said that the hall was filled with the spirits of dead warriors. Odin did not house these warrior spirits out of respect but most of those to whom he granted access to were distinguished warriors whom he collected for the selfish purpose of having them aid him in his foredoomed struggle against the wolf Fenrir during Ragnarok.
There were supposed to be 540 gates, which were wide enough to let in 800 men at one time. With the hall’s ceiling thatched with golden shields and spears for protection.
