Rivendell

Rivendell (Sindarin: Imladris) is an Elven outpost in Middle-earth, a fictional realm created by J. R. R. Tolkien. It was established and ruled by Elrond in the Second Age of Middle-earth (four or five thousand years before the events of The Lord of the Rings). In addition to Elrond and his family, notable Elves who lived there included Glorfindel and Erestor.

Rivendell is a direct translation or calque of the Sindarin name Imladris, both meaning "deep valley of the cleft".
