Flak towers (German: Flaktürme) were large anti-aircraft gun blockhouses used by the Luftwaffe to prevent overflights of key areas in certain cities in World War II. They also served as air-raid shelters for tens of thousands of people and to coordinate air defence. With concrete walls up to 3.5 metres thick, these towers were considered to be invulnerable to attack with the usual ordnance carried by Allied bombers, though it is unlikely that they would have withstood Grand Slam bombs which successfully penetrated much thicker reinforced concrete. Aircraft generally appeared to have avoided the flak towers.

The Soviets, in assaulting Berlin, found it hard to make an impression on the Flak towers, even with some of the largest Soviet assault guns, the 203 mm howitzers. Soviet forces generally manoeuvered around them, and eventually sent in envoys to seek their submission. Unlike the rest of Berlin, the towers tended to be stocked with ammunition, and used their anti-aircraft 20 mm cannons to attack ground units. The Zoo Tower was one of the last points of defence, with German armoured units rallying near it at Tiergarten, before trying to break out of the encircling Soviet Red Army.

The towers, during the fall of Berlin, formed their own communities. Being some of the safest places in the fought-over city, they were usually crammed with civilians, eventually forcing them to capitulate as supplies ran out.

For a time after the war, the conversion to representative objects with decorated facades was planned. After the war was lost, the demolition of the towers was in most cases unfeasible and many remain to this day.

[edit] Flak Tower generations

Each Flak tower complex consisted of a G-Tower (German: Gefecht Turm) or Combat Tower, also known as the Gun Tower, Battery Tower or Large Flak Tower, and a L-Tower (German: Leit Turm) or Lead Tower also known as the Fire-control tower, command tower, listening bunker or small flak tower.

The three generations of G tower.
  • Generation 1
    • G-Towers were 70.5 × 70.5 × 39 m, usually armed with eight (four twin) 128 mm guns and numerous 37 mm and thirty-two (eight quad) 20 mm guns.
    • L-Towers were 50 × 23 × 39 m, usually armed with sixteen (four quad) 20 mm guns.
  • Generation 2
    • G-Towers were 57 × 57 × 41.6 m, usually armed with eight (four twin) 128 mm guns and sixteen (four quad) 20 mm guns.
    • L-Towers were 50 × 23 × 44 m, usually armed with forty (ten quad) 20 mm guns.
  • Generation 3
    • G-Towers were 43 × 43 × 54 m, usually armed with eight (four twin) 128 mm guns and thirty-two (eight quad) 20 mm guns.

The evaluation of even larger Battery Towers was commissioned by Adolf Hitler. These would have been three times the size and firepower of Flak towers.

  • Augarten (3rd Generation)
    • G-Tower remains empty. The entire north-east and half of the east machine gun platforms have been removed during 2007 including the connecting walkways due to deterioration. The tower itself has been reinforced with steel cables encircling the entire structure, 12 cables are located above the machine gun nests, 6 just below, and an additional 4 midway up the tower. The tower is home to thousands of pigeons which nest on every platform and opening. The west side of the structure is also used as a cellular communications tower. 48.22563° N 16.372815° E
    • L-Tower remains empty. Its use as a computer storage facility or an open air cinema is being considered, , 48.227896° N 16.377992° E
