Bunkers del Carmel

This guide to Bunkers del Carmel in Barcelona starts with a tile fragment still pressed into the dirt underfoot, and traces the hill's two lives before it became a viewpoint. It covers the anti-aircraft battery the Republic mounted here in 1938 as the city endured one of history's first systematic bombing campaigns against civilians, and the families who later moved onto the hill and built a settlement called Els Canons out of the wartime concrete. Listen for how long that settlement lasted, and why it finally emptied out.
