A wardrobe transports the Pevensie children into Narnia in C.S. Lewis’s first-published Narnia novel. The Lion, the Witch and the Wardrobe begins when Lucy Pevensie discovers that an old wardrobe opens into another world.
Lucy first enters the snowy wood beyond the wardrobe and meets the faun Mr. Tumnus. Her siblings Peter, Susan, and Edmund later enter Narnia as well, and the children become involved in the struggle against the White Witch.
The wardrobe is not simply a doorway placed anywhere in the story: it is a significant object connected with the house in which the children are staying during wartime. The novel’s title names both the object and the central antagonist, the White Witch.
The book was published in 1950 and was the first Narnia book released to readers, although modern editions often arrange the series according to internal chronology, beginning with The Magician’s Nephew. That publication-order difference explains why descriptions of the “first” Narnia book can vary.
