Rivendell

The hidden refuge of Elrond Halfelven, founded by Elrond in the Second Age against the assaults of Sauron in Eriador. It lay in a deep valley in the western foothills of the Misty Mountains, and endured, under the protection of Elrond’s Ring Vilya, until the War of the Ring and beyond. After the War, the Ring’s power ended and Elrond passed over the Sea, but Rivendell itself remained, at least for a time, in the keeping of Elrond’s sons Elladan and Elrohir.
