In World War 2 Germany constructed several “Flak Türme” or in English Flak Towers. There were located in 3 cities, namely, Berlin, Hamburg and Vienna. Many of them actually survived up to this day, because they were usually too difficult to destroy. For instance, in Vienna all 6 are still standing and they were also the most modern ones. Military History Visualized provides a series of short narrative and visual presentations like documentaries based on academic literature or sometimes primary sources.
