The Refugio Antiaéreo de la Guerra Civil Española is a civil defense air raid shelter located on Calle de Reina Victoria in Santander, Spain. Built during the Spanish Civil War (1936-1939), this bunker was constructed to protect the civilian population from aerial bombardments that targeted the city. The structure represents the widespread network of air raid shelters built across Spain during this conflict, when cities like Santander faced repeated attacks from both Nationalist and Republican air forces.
The shelter is situated in the coastal city of Santander, the capital of Cantabria in northern Spain. As a strategic port city, Santander was vulnerable to air raids during the war, making such protective structures essential for civilian safety. The Refugio Antiaéreo de Reina Victoria stands as a testament to the urban warfare tactics of the 1930s and the impact of aerial bombardment on civilian populations during the Spanish Civil War.
