In Norse mythology, Valhalla (from Old Norse Valhöll "hall of the slain") is a majestic, enormous hall located in Asgard, ruled over by the god Odin. Chosen by Odin, those that die in combat travel to Valhalla upon death, led by valkyries. There, they join the masses of the dead who have died in combat known as Einherjar, as well as various legendary Germanic heroes and kings, as they prepare to aid Odin during the events of Ragnarök. Before the hall stands the golden tree Glasir, the hall's ceiling is thatched with golden shields, and various creatures live around it, such as the stag Eikþyrnir and the goat Heiðrún, both described as standing atop Valhalla and consuming the foliage of the tree Læraðr.Valhalla is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, written in the 13th century by Snorri Sturluson, in euhemerized form and as an element of remaining Norse pagan belief in Heimskringla, and in stanzas of an anonymous 10th century poem commemorating the death of a Eric Bloodaxe known as Eiríksmál as compiled in Fagrskinna. Valhalla has inspired various works of art, publication titles, and has become a term synonymous with a martial (or otherwise) hall of the chosen dead.
