The Refugi Antiaeri de la Plaça Revolució is a civil war air raid shelter located in the Gràcia district of Barcelona, Spain. Built during the Spanish Civil War, this underground refuge was designed to protect local residents from aerial bombardments that targeted the city. The shelter forms part of a network of defensive structures constructed throughout Barcelona to safeguard civilians during the conflict.
The shelter features brick-lined walls and ceilings, with narrow tunnels that create an intimate yet claustrophobic atmosphere. Historical elements remain intact, including stone benches where people would have sat during alerts, basic sanitary facilities, and evidence of candle smoke on the walls from when the space was illuminated during air raid warnings. The site preserves the authentic atmosphere of wartime civilian life and the daily reality of seeking protection from enemy aircraft.
