Rivendell ( Sindarin : Imladris ) is an Elven outpost in Middle-earth , a fictional realm created by J. R. R. Tolkien . It is also referred to as 'The Last Homely House East of the Sea', alluding to Valinor , which is west of the sea. It was established by Elrond in the Second Age of Middle-earth (four or five thousand years before the events of The Lord of the Rings ). Besides Elrond himself, notable Elves who live there include Arwen and Glorfindel .
