Mmm...Bunkers
Here's an lovely set of bunker photos for your delectation...
"Walking along the beach some years ago, I noticed a dark structure emerging from the mist ahead of me," J.G. Ballard writes. "Three storeys high, and larger than a parish church, it was one of the huge blockhouses that formed Hitler's Atlantic wall, the chain of fortifications that ran from the French coast all the way to Denmark and Norway. This blockhouse, as indifferent to time as the pyramids, was a mass of black concrete once poured by the slave labourers of the Todt Organisation, pockmarked by the shellfire of the attacking allied warships."
"These bunkers were part of a system of German fortifications that included the Siegfried line, submarine pens and huge flak towers that threatened the surrounding land like lines of Teutonic knights. Almost all had survived the war and seemed to be waiting for the next one, left behind by a race of warrior scientists obsessed with geometry and death."
