Children enter the fictional world of Narnia through a wardrobe in C.S. Lewis's novels. The doorway appears most famously in The Lion, the Witch and the Wardrobe, published in 1950.
The wardrobe stands in Professor Kirke's country house, where Peter, Susan, Edmund, and Lucy Pevensie are evacuated during the Second World War. Lucy discovers that its back opens onto a snowy wood in Narnia. The series eventually expands to seven novels, describing Narnian history across many centuries.
Narnia is inhabited by talking animals, fauns, dwarfs, giants, and other creatures. Aslan, a talking lion and creator figure, is the central recurring character. Readers sometimes assume the wardrobe is the permanent entrance in every book, but later stories use other portals, including magical rings and a painting.
Lewis arranged the books for publication beginning with The Lion, the Witch and the Wardrobe. The internal chronology begins with The Magician's Nephew, which depicts Narnia's creation, so publication order and story chronology differ.
