RivendellRivendell - Elven city west of the Misty Mountains founded by Elrond in the Second Age after Eregion was destroyed by Sauron.

 

"From that time war never ceased between Sauron and the Elves; and Eregion was laid waste, and Celebrimbor slain, and the doors of Moria were shut.  In that time the stronghold and refuge of Imladris, that Men called Rivendell, was founded by Elrond Half-elven; and long it endured." ~The Silmarillion (Of the Rings of Power and the Third Age)

 

"At this time the first Council was held, and it was there determined that an Elvish stronghold in the east of Eriador should be maintained at Imladris rather than in Eregion.  At that time also Gil-galad gave Vilya, the Blue Ring, to Elrond, and appointed him to be vice-regent in Eriador..." ~Unfinished Tales (The History of Galadriel and Celeborn)
