The Santander Air Raid Shelter (Refugio Antiaéreo) is a unique historical museum located in an authentic air raid shelter from the Civil War era. Situated in the very center of the city, this site in Spain serves as a living historical monument, allowing visitors to literally touch the past and feel the atmosphere of the turbulent 1930s.

This compact structure, measuring approximately 68 square meters, was originally intended to protect the government and high-ranking officials. It was only rediscovered in 2006 and, after a thorough restoration, was transformed into a modern museum space. Inside, the authentic corridors and compartments have been preserved and are now filled with thematic exhibits.
Today, the museum offers guests an emotional immersion through the personal stories of residents and unique exhibits: from a 240-kilogram aerial bomb to a mannequin of a German pilot. Thanks to masterful work with lighting and sound, Refugio Antiaéreo is considered one of the city's most impressive and significant attractions, telling a story of resilience and daily life under extreme conditions.
