Study › Runes & Norse › Asgard

Asgard is the home of the Aesir, the main family of Norse gods, and one of the nine worlds of Yggdrasil. It is ringed by a great wall, reached only over the rainbow bridge Bifrost, and holds the gods' halls, among them Odin's Valhalla.
What is Asgard in Norse mythology?
Asgard is the fortified home of the Aesir, the principal tribe of Norse gods. It sits high in the branches of Yggdrasil and is ringed by a great wall, built (as one myth tells) by a giant mason whom the gods cheated of his payment. The rainbow bridge Bifrost is the only road that leads up to it.
The halls of Asgard
Within Asgard lie the gods' many halls: Odin's Valhalla, where slain warriors feast; his high seat Hlidskjalf, from which he sees across all worlds; Thor's Bilskirnir; and the meadow of Fensalir and the fields where the gods hold their assembly at the Well of Urd. Asgard stands for order and rulership in the myths, forever pitted against the wild forces of Jotunheim.
Ruled by: Odin, the Allfather and chief of the Aesir.
Its best-known hall is Valhalla; its watchman is Heimdall; it stands in Yggdrasil, the World Tree.
