Strange Towers of the Third Reich
‘These concrete towers were unique AIR RAID SHELTERS of Nazi Germany, built to withstand the destructive power of WWII bombs and heavy artillery. Their cone shape caused bombs to slide down the walls and detonate only at a heavily fortified base.
Cheaper to build above ground than to dig bunkers, they were quite effective, as it was possible to cram as many as 500 people inside. Plus the “footprint” of such tower was very small when observed from the air, so it was very hard for the bombers to ensure a direct hit.’
