Commission for Organising the Fortified Regions



The Commission for Organizing the Fortified Regions (French: La Commission d'organisation des régions fortifiées (CORF)), is a French military organization created on 30September 1927 by the Minister of War Paul Painlevé to study and carry out border fortification. Its creation was not a spontaneous decision but the result of a long and deep reflection on how best to defend the borders of France.

The acronym CORF also refers to a type of fortification, be it ouvrage (earthwork), bunker, observatory or shelter, whose plans were drawn up by the Commission and form the most powerful part of the Maginot Line.
