"And there where the White Mountains of Ered Nimrais came to their end he saw, as Gandalf had promised, the dark mass of Mount Mindolluin, the deep purple shadows of its high glens, and its tall face whitening in the rising day. And upon its out-thrust knee was the Guarded City, with its seven walls of stone so strong and old that it seemed to have been not builded but carven by giants out of the bones of the earth."J. R. R. Tolkien: The Lord of the Rings, the Return of the King. Book V, Chapter 1: Minas Tirith
Wow, incredible work.
Took everything Sauron could throw at it for centuries... Nice angle, it would be a tremendous illustration.
