Catalonia is a land of bombs. Many were suffered by its population, and many others wait buried in the mud of the Ebro River, or under a false roof of a monastery of cloistered nuns.

“Between 10 and 20% of the unexploded devices that were launched in the Civil War did not work and some of them are distributed throughout the territory,” explains the Catalan police. The oldest ones in the Mossos files date back to 2001, when a fisherman in Roses came across an underwater gold mine from the Second World War.
