High atop Turó de la Rovira hill sits the historic Bunkers del Carmel in the district of El Carmel. The bunkers were built in 1937 during the Spanish Civil War as an anti-aircraft fort to defend against attacks on the city. Today you can find bulky 105 mm cannons mounted on the concrete walls and various gaping holes and crumbling walls. After the war, the bunkers served as a shelter for citizens and had as many as 3,000 residents in the 1960s. In the 1990s, the Barcelona City Council rehoused the residents of the bunkers to flats within the city in an effort to “clean up” the city for the 1992 Olympics. The bunkers were practically forgotten during most of the 1990s and 2000s until 2011 when the Carmelite Agency and the Museu d’Historia de Barcelona (MUHBA) underwent a project to restore the bunkers and improve accessibility. Now the bunkers have become an increasingly popular destination to visit with its breathtaking view of Barcelona. The panoramic scene is host to many photos, picnics, music sessions and hangouts in the city.
