On June 12, 1937, the so-called “Iron Ring” of Bilbao (Bizkaia) was bombarded and finally destroyed by the armed forces of Francisco Franco. The “Iron Ring” was a series of fortifications made primarily of steel and concrete. Constructed between 1936 and 1937, the purpose of this structure was to defend the city of Bilbao, which was an important  industrial center for the Republican Army during the Spanish Civil War. The breakthrough of this fortified line left the Bizkaian city unprotected. In the next few days, Franco’s troops advanced northward through the Basque territory and, finally, on June 19, took Bilbao.
