Croissant pouvre is a French term for the suburbs least likely to be settled by the European middle classes. Translated literally, it means ‘poor crescent’. This description has nothing to do with the perennial breakfast favourite — it is a word-play on the origin and favoured symbol of the majority of residents in these suburbs. Paris, Brussels, Copenhagen, Stockholm, Berlin – most large European cities have these ‘no-go’ areas, which also have another description – ‘zones sans-droit’: zones without law. Simply put, the law of the land does not apply. Instead, Sharia is firmly in control. France has about 30 zones sans-droit, all of which share three characteristics.
