Some nights were spent waiting for morning underground

End inside the idea of darkness rather than outside it. Refugi 307 was excavated through the work of Poble-sec residents as Barcelona built a dense Civil War shelter network against aerial bombing. MUHBA documents almost 400 metres of tunnels with toilets, water, an infirmary, a children's room and a fireplace — facilities that make sense when sheltering is more than a quick interruption. Barcelona's archaeology service is explicit about the human rhythm: shelters had to be organised because residents often spent whole nights underground. You do not need to enter the museum to understand the exterior entrance as a threshold between ordinary street life and a second city created for survival. The route began with people working before dawn. It ends with people waiting below ground for dawn to be safe enough to return.
