Krupp decoy site

It was designed to divert Allied night airstrikes in the bombing of Essen in World War II from the actual production site of the arms factory.

[1] The dummy factory was supposed to mimic a poorly darkened and operating Krupp steel works as the Royal Air Force only flew at night.

The decoy system consisted of a large number of very rudimentary dummy installations of industrial building and structures.

Among them were shed roofs, a gasometer, chimneys, a railroad, and elaborate light arrays and fires, controlled from a nearby bunker.

Visits are offered on the European Heritage Days, historical walks or the Long Night of Museums.
