Chapter 6
Non-Operational National Prisons:

      Before World War II, two national prisons were established by the government which are no long operational. One was on Corregidor Island and the other in the Mountain Province.

      In 1908 during the American regime, some 100 prisoners were transferred from the Old Bilibid Prison to the Corregidor Island Prison Stockage to work under military authorities. This move was in accordance with an order from the Department of Instructions, which approved the transfer of inmates so they could assist in maintenance and other operations in the stockade.

      The inmates were transported not to serve time but for prison labor. Until the outbreak of the Second World War, inmates from Bilibid Prison were regularly sent to Corregidor for labor purposes. When the War broke out, prisoners on Corregidor were returned to Bilibid Prison. The island prison was never re-opened.

      The Philippine Legislature during the American regime also passed Act No. 1876 providing for the establishment of a prison in Bontoc, Mountain Province. The prison was built for the prisoners of the province and insular prisoners who were members of the non-Christian tribes of Mountain Province and Nueva Viscaya.

      The Bontoc prison could be reach only through narrow, poorly developed mountain roads. Due to the enormous expenses incurred in transporting personnel, equipment and supplies to the prison, the facility was abandoned and officially closed on April 26, 1932.
