A wardrobe transports the Pevensie children into Narnia in C.S. Lewis's The Lion, the Witch and the Wardrobe.
Lucy Pevensie discovers the passage while exploring a large wardrobe in a spare room of an old country house. At first, her siblings doubt her account, but all four children eventually pass through the wardrobe and enter the snow-covered wood of Narnia.
The wardrobe is more than a magical doorway: it is the central image that connects the ordinary world of wartime Britain with Lewis's imagined world. The children are staying in the countryside because they have been evacuated from London during the Second World War.
Readers sometimes confuse this entry point with other portals in the series. The Magician's Nephew uses magical rings and a pool between worlds, while later stories use a painting, a stable, and other forms of transition. The wardrobe is specifically associated with the first published Narnia novel.
