The plain is the location of many of the Valar's lands and personal dwellings. It most notable feature was the city of Valmar, of many bells which was located in the east-central part. South of Valmar were the Pastures of Yavanna and the Woods of Orome. Other features were the Gardens of Lorien, the Great Court of Aulë, and the dwelling of Nienna in the far west. Beneath the Plain of Valinor were the vast interconnecting tunnels that made up the Halls of Mandos.
