Elysium

This word came into Latin from the Greek Elysion. In classical mythology, Elysium, or the Elysian fields, was the home of the blessed after death, the final resting place of the souls of the heroic and the pure. So it's easy to see how the word came to mean any place or state of bliss or delight. When we try to picture heaven, many of us probably see a lovely park; the great boulevard of Paris was named for the beautiful park that originally bordered it: the Champs-Elysées, or Elysian Fields.
