It's not just the picturesque locations or the stout Brutalist architecture that makes them beautiful -- though it helps -- it's the fact that nearly every one of them is rotting from disuse. Our friends at Oobject have assembled a collection of nine of these incredible pillboxes.
19th Century Dutch Bunker -- Split
Making a folly out of this by slicing a path right through it also serves to show just how little space there is behind the extremely thick walls of a bunker.
Alan Williams Turrets from British WWII defences
Most of the British bunkers were architecturally uninteresting apart from this notable exception.
Beached WWll Concrete Bunker -- Cape May
This bunker was mostly underground till erosion exposed it like a giant concrete wreck.
Bunker Archaeology by Paul Virilio
Paul Virillo's famous images of the accidental architecture of the 12,000 bunkers that formed the Atlantic Wall.
Decoy bungalow, Kelvedon Hatch Nuclear Bunker
This cold war bunker in the UK, intended as a regional HQ in case of nuclear attack, had a replica suburban bungalow to conceal its entrance.
Japanese bunker defence in sunken ships

A spherical concrete bunker for one person.

Can this possibly be true? Apparently there are 750K abandoned concrete bunkers in Albania, remnants of paranoid, xenophobic, Communist dictator, Enver Hoxha.
The Camouflaged Bunkers of Switzerland

US bunkers in Marin headlands
Built against a possible Japanese invasion during WWII, these are just outside San Francisco
Very strange highly conspicuous air raid shelters that are often converted into everything from bus stops to night clubs.
