Archaeological digs at the former Albatera Civil War concentration camp aim to confirm the testimonies of witnesses that thousands of prisoners were subjected to extreme mistreatment at the facility. Originally a work camp built by the Republic in 1937 for up to 2,000 Nationalist prisoners, it was turned into the largest prisons of its kind after the war by Franco’s forces, holding almost 15,000 men at the 13-hectare site in San Isidro.
