Annwn or Annwfn (Midle Welsh Annwvn, sometimes inaccurately written Annwyn, Annwyfn or Annwfyn) was the Otherworld in Welsh mythology. Ruled by Arawn, or much later by Gwynn ap Nudd, it was essentially a world of delights and eternal youth where disease is absent and food is ever-abundant. It later became Christianised and identified with the land of souls that had departed this world.
