Join a guided tour of Refugi 307 in the Poble-sec neighborhood to learn how the community built the 200 meters of tunnels excavated in the mountain and how those who had to take refuge lived there. Various rooms such as bathrooms, a fountain, a infirmary, a children's room, and a fireplace can be observed; the refuge has been restored and opened to the public to show the consequences of wars.
