Rivendell, or Imladris, was an Elven outpost in the Misty Mountains on the eastern edge of Eriador.

Because of its location, it was called the Last Homely House from the point of view of a traveller going to the Misty Mountains and Wilderland; and also the First Homely House from the point of view of someone coming from these lands to the civilised lands of Eriador to the west. It was established by Elrond in S.A. 1697 as a refuge from Sauron after the Fall of Eregion. It remained Elrond's seat throughout the remainder of the Second Age and until the end of the Third Age, when he took the White Ship for Valinor. Rivendell had a strong alliance with the Kings of Arnor and after the fall of Arthedain, it became a refuge for the Rangers of the North and the Heir of Isildur. Rivendell was located at the edge of a narrow gorge of the Bruinen River, but well hidden in the moorlands and foothills of the Misty Mountains. Pine-trees grew on the top of the valley, and there was a "steep zig-zag path" to the valley bottom. The vegetation in the valley bottom was mostly oak and beech.
