Tree of Protection

''It must have grown up silently, yet swiftly as a flag rises when you pull it up on a flagstaff, while they were all busied about the coronation. It spreading branches seemed to cast a light rather than a shade, and silver apples peeped out like stars from under every leaf. But it was the smell which came from it, even more than the sight, that had made everyone draw in their breath. For a moment one could hardly think about anything else.''

The Tree of Protection was a beautiful magical tree that bore as fruit silver apples, planted in what would become the Lantern Waste by Digory Kirke during the creation of Narnia; it was the direct offspring of the Tree of Youth. It protected Narnia from all evil for approximately nine hundred years, specifically from Jadis, the White Witch, after she fled to the north. It is possible that the death of this tree is the event which allowed the White Witch to return to conquer Narnia and impose the Long Winter (during which, the climate prevented any further magical trees from being grown).

The Tree
The Tree itself did not have the power to repel Jadis, but rather, she despised its fruit to such an extent (after having eaten, wrongfully, the same fruit from the Tree of Youth) that she could not be within a hundred miles of that Tree, or any other related one, or else she would be plighted with a dreadful sensation of misery. Aslan himself described the smell of the Tree as "joy and life and health" to all good Narnians, but "death and horror and despair" to Jadis.

Though the Tree of Protection refers singularly to the tree planted on the banks of the Great River in Lantern Waste, there were at least three other trees that were directly related to that tree. The first was the Tree of Protection’s parent, the Tree of Youth, found in the centre of the hilltop garden in the Western Wild at the Dawn of Time. This is the tree that Aslan sent Digory to pluck an apple from, and bring it back to Narnia to plant the Tree of Protection.

The second Tree was the tree planted in London, England, which was a direct offspring of the actual Tree of Protection, having grown from the planted core of a magic apple from that Tree. This tree, being in our world and far from the air of Narnia, was not entirely magic. It looked the same as a regular apple tree, only that it bore apples more beautiful than any others in England, and they were extremely good for one. However, deep within that tree, in its very sap, it was still connected to its parent in Narnia; in fact, it would even tremble and move by itself when there were large winds blowing on the Tree of Protection. Eventually, the tree in London fell during a great storm, and Digory (now a famous learned man, a great traveller, and a middle-aged professor) had its wood made into a Wardrobe, which would later be found by Lucy Pevensie to be a portal into Narnia.

The third Tree (technically first) was the real creation of the original Tree in the garden. It was in the center of a sacred garden of Aslan's Country, and there too it was guarded by the Phoenix. King Frank I and Queen Helen sat beneath it at the Great Reunion.
