In C.S. Lewis’s Narnia, what object serves as the portal from England?

In C.S. Lewis’s Narnia, a wardrobe serves as the portal from England. In The Lion, the Witch and the Wardrobe, Lucy Pevensie discovers that the back of an old wardrobe opens into a snowy woodland in Narnia.

The wardrobe belongs to Professor Kirke, whose large country house shelters the four Pevensie children during the Second World War. Lucy enters first, followed by Edmund, Peter, and Susan, and their arrival becomes part of Narnia’s struggle against the White Witch.

The wardrobe is often remembered as a general fantasy doorway, but its role is specific to this novel. Other Narnia books use different routes between worlds, including magical rings, a painting, and a railway accident.
