In J. R. R. Tolkien's legendarium, Lothlórien is the fairest forest realm of the Elves remaining in Middle-earth during the Third Age.
The realm plays an important part in The Lord of the Rings as the Elven centre of resistance against Sauron and is a symbol for the Elves' aesthetics of preservation which provides a space 'out of time' for the characters who both live and visit there. With Lothlórien, Tolkien reconciles otherwise conflicting ideas regarding time-distortion in Elfland from various traditional sources such as Thomas the Rhymer (13th/14th C.) and the Danish folk-play Elverhøj (1828).
