In Norse myth, the hall where slain warriors feast until Ragnarök is Valhalla.
Valhalla, or Valhǫll in Old Norse, is Odin’s great hall in Asgard. Valkyries choose some of those who die in battle and bring them there as the einherjar, the honored battle-dead. Each day, these warriors fight one another, rise again, and return to feast and drink.
Their feasting is preparation rather than simple reward. At Ragnarök, the einherjar are expected to ride out with Odin for the final battle against the forces of chaos. The hall’s mythical provisions include the boar Sæhrímnir, whose meat is renewed, and mead supplied by the goat Heiðrún.
A common mix-up is treating Valhalla as the destination for every dead person or every battlefield casualty. Norse sources also describe Freyja’s Fólkvangr as receiving some of the slain, while Hel is a different realm for many of the dead. Even so, Valhalla is the canonical answer to the familiar quiz description of warriors feasting before Ragnarök.
