A fake Paris was partially constructed near the real Paris at the end of World War I in the hopes of confusing German planes who were looking to bomb the City of Lights.
The story of Sham Paris may have been "broken" in The Illustrated London News of 6 November 1920 in a remarkably titled photo essay, "A False Paris Outside Paris — a 'City' Created to be Bombed". There were to be sham streets lined with electric lights, sham rail stations, sham industry, open to a sham population waiting to be bombed by real Germans. It is a perverse city, filled with the waiting-to-be-murdered in a civilian target.
