§ Of the Beginning of Days The Silmarillion

Behind the walls of the Pelóri the Valar established their domain in that region which is called Valinor, and there were their houses, their gardens, and their towers. In that guarded land the Valar gathered great store of light and an the fairest things that were saved from the ruin; and many others yet fairer they made anew, and Valinor became more beautiful even than Middle-earth in the Spring of Arda; and it was blessed, for the Deathless dwelt there, and there naught faded nor withered, neither was there any stain upon flower or leaf in that land, nor any corruption or sickness in anything that lived; for the very stones and waters were hallowed.
