Background

The Concordat Prison (in Spanish, Cárcel Concordataria) refers to the prison that the Francoist State in Spain operated for dissident Catholic priests. It was a pavilion of the provincial prison of Zamora. The Concordat of 1953 allowed that jailed priests did their time in religious houses, but conservative convents were not pleased to take leftist priests and progressive convents could sympathize with the prisoner. Lots of the prisoners were Basques. Already in the Spanish Civil War, Basque nationalist priests had rejected the rebels.
