So they came to the Golden Gate, the last of the ancient gates of Turgon that were wrought before the
Nirnaeth; and it was much like the Gate of Silver, save that the wall was built of yellow marble, and the globes
and parapet were of red gold; and there were six globes, and in the midst upon a golden pyramid was set an
image of Laurelin, the Tree of the Sun, with flowers wrought of topaz in long clusters upon chains of gold.
And the Gate itself was adorned with discs of gold, many-rayed, in likenesses of the Sun, set amid devices of
garnet and topaz and yellow diamonds. In the court beyond were arrayed three hundred archers with long
bows, and their mail was gilded, and tall golden plumes rose from their helmets; and their great round shields
were red as flame.
From The Unfinished Tales, Of Tuor and his Coming to Gondolin
I like that description of a tree, Laurelin he was once called. Not to forget the female tree you still can visit in a courtyard of the University in Oxford next to him … anyway, this doesn’t really matter …
