Barcelona, a city renowned for its sun-soaked beaches, Gaudí’s mesmerizing architectural wonders, and vibrant street life, holds a mysterious and darker history beneath its bustling streets. As visitors and residents traverse the city’s historic avenues and narrow alleyways, many remain oblivious to the secret bunkers and shelters lying underneath, remnants from a tumultuous period in Spain’s history.
During the Spanish Civil War, from 1936 to 1939, Barcelona was subjected to relentless aerial bombings, and its populace lived in constant dread. The looming threat prompted the construction of over 1,400 air raid shelters throughout the city. These safe havens were primarily built by the city’s inhabitants, often by hand, reflecting a community-driven initiative to safeguard their families and neighbors. One of the most emblematic and well-preserved of these shelters is Refugio 307 in the Poble Sec district. This extensive network of tunnels, outfitted with infirmaries, toilets, and even a fountain, offers a haunting portrayal of life during the bombings. Ambient sounds of sirens and era-appropriate radio broadcasts in these dimly lit passages transport visitors back to those perilous times.
As the war concluded and the city began its healing process, many of these underground structures were left abandoned, forgotten, or repurposed for new uses. Only in recent times has there been a renewed interest in these bunkers. A notable number are undergoing restoration and reopening to the public, standing as stark reminders of Barcelona’s resilience and the indomitable human spirit. Additionally, the hills of El Carmel are home to the Bunkers del Carmel, a former anti-aircraft battery station. Originally built for wartime defense, these bunkers now provide one of the city’s most panoramic views, frequented by locals and tourists during sunrise and sunset, symbolizing a transformation from war relics to places of beauty and reflection.
For those eager to explore this concealed aspect of Barcelona, it’s advisable to wear comfortable footwear and approach with reverence. While many bunkers can be accessed freely, some, like Refugio 307, have specific visiting hours and entry fees, managed by the Museu d’Història de Barcelona (MUHBA). In essence, while Barcelona’s surface-level attractions are undeniably enchanting, delving into its underground past offers a profound understanding of the city’s narrative, highlighting its enduring spirit and rich tapestry of resilience and hope.
