Gondor's geography is illustrated in the maps for "The Lord of the Rings" and "Unfinished Tales" made by Christopher Tolkien on the basis of his father's sketches, and geographical accounts in "The Rivers and Beacon-Hills of Gondor", "Cirion and Eorl", and "The Lord of the Rings". Gondor lies in the west of Middle-earth, on the northern shores of Anfalas and the Bay of Belfalas with the great port of Pelargir near the river Anduin's delta in the fertile and populous region of Lebennin, stretching up to the White Mountains (Sindarin: "Ered Nimrais", "Mountains of White Horns"). Near the mouths of Anduin was the island of Tolfalas.
