Mindolluin

Mindolluin or Mount Mindolluin, is a mountain in Middle-earth, easternmost peak of the Ered Nimrais (White Mountains), below and to the east of which stands the city of Minas Tirith. Its name is Sindarin for "towering blue head"; the double "l", as with all double letters in Sindarin, is pronounced as two separate letters rather than one.

In The Return of the King, shortly after Aragorn's coronation as King Elessar, Gandalf takes him by an ancient path into the foothills of Mindolluin, far above the city. There he discovers, upon an otherwise barren slope, a sapling of Nimloth, the White Tree of Gondor, which he plants in the Court of the Fountain as a sign of rebirth.
