Somewhat justifiably, before the Second World War, France feared invasion from Germany. So it built the Maginot line on the German frontier. The defences turned out to be useless as the Germans simply bypassed them.
Franco thought much the same about Germany, so he built the “Linea P” in the Pyrenees to defend Spain, firstly from the Nazis, then from the Allies and Spanish Republicans who might have invaded in 1945. Although it was somewhat thin – the locals called in the “linea como si no – the line which wasn’t there” – the bunkers still survive. The story is told by M Chevaux (in French):
