- "It is very foolish to shut one-self into any wardrobe. "
- ―C.S. Lewis
During that adventure, Aslan had sent Digory to retrieve an apple from a magic tree and bring it back to him. After Digory did so, the apple was planted in the ground and grew into a beautiful tree with silver bark, known as the Tree of Protection. This tree acted like a shield, keeping the witch Jadis out of Narnia for many years after it was planted.
Aslan later gave an apple from the Tree of Protection to Digory. When he returned to London and gave the apple to his mother who, after eating it, was cured of her long and debilitating sickness. Afterwards, Digory buried the apple core in his backyard, and it grew into a tree as well - a daughter tree to the one that had grown in Narnia. Sometimes the apple tree would creak and move, as if being blown in the wind - when there wasn't any; as if it could feel the winds that blew its mother tree.
Portal to Narnia
Eventually, the tree was blown down in a storm, and the much older Digory, unable to bear the prospect of the magical tree being simply chopped up for firewood, had the wood from the tree made into a beautiful wardrobe. This was placed in the empty back room of his large country home, where many years later, Lucy Pevensie discovered it while exploring the house with her siblings.
The portal seemed not to be open all the time, because when Lucy returned and tried to show the other children, they found only an ordinary wardrobe, with a solid back.
The wardrobe portal was used twice more, first by Lucy and Edmund, who had separate adventures, and then finally all four children entered together. They saved Narnia from the White Witch, and ruled Narnia for 15 years during the Golden Age.
They eventually came back through the wardrobe the same way, and became children again, but told the Professor about all of their adventures. He said they might return to Narnia someday, but suggested they not try to get into Narnia by that route again.

- Author C. S. Lewis had an English country home of his own, and he took in children who were fleeing London because of the German air-raids, much the same as the Professor did. He also had a magnificent wardrobe in an upstairs room, said to have been of particular interest to one little girl, and to have inspired the wardrobe for which Lewis is now known.
