Shortly before the end of the works on the Valle de los Caídos, the Franco regime tried to adapt its original function, to house the remains of its "heroes and martyrs", to turn the monument into a symbol of reconciliation of all the "fallen" in the Civil War.

The article analyses this new concept and documents its use when it comes to identifying the victims of Franco's repression at the time of their transfer to the monument.
