Map of Aman

" So they left Middle-earth and went to the Land of Aman, Far West territory to the edge of the world. Its shores are washed by the Outer Sea, that the Elves call Ekkaia and around the Kingdom of Arda. No one knows except the Valar, the extent of the sea, which leads to the Walls of the Night. On the east coast of the Land of Aman had finished Belegaer, Great Western Sea, and Melkor was like on Middle-earth and they could not overthrow the Valar fortified their home raising near the coast the Pelóri, the highest mountains of the world. " The Silmarillion
