View inside Holy Trinity Church, Headington Quarry in Oxford, England. It is an active Anglican parish church in the Diocese of Oxford.  The church, designed by George Gilbert Scott, was built in 1848–49, to serve the spiritual needs of those living and working in the then-active quarry. Its foundation stone was laid on 19 June 1848 by Samuel Wilberforce, the son of William Wilberforce and then Bishop of Oxford, who consecrated the building on completion.

The Lewis brothers, C. S. Lewis and Warren Lewis, began attending here in 1930 and remained active in this church until their deaths, C. S. Lewis in 1963 and W. H. Lewis in 1973.  The church is known for its Narnia window, which features images from C. S. Lewis's Chronicles of Narnia.  The window contains a lamp post, the word "Narnia," Glimfeather the owl, the flying horse Fledge, the sword, shield, and bottle of cordial from the story of The Lion, the Witch and the Wardrobe, the Dawn Treader, the castle Cair Paravel, Susan's horn and bow with quiver, and talking animals. In the top left and right hand corners are the arms of John Williams, 1st Baron Williams of Thame, who founded Lord Williams's School which Willie attended at the time of his death.
