Luftschloss imaginatively and deliberately destructs a nazi bunker that nowadays still towers over Vienna. In 1942 Hitler himself gave the orders to erect several 55m tall Flak towers to protect the historic city of Vienna. These colossal concrete castles were meant to become symbols of a victorious Third Reich. The way Europe deals with such historically burdened heritage has paradoxically led to the conservation of its original intention. The seeming indestructible castles still tower over the city. Until today.

The short film was made by mixing filmed images of the hydro‑demolition of reinforced concrete (3 x 2 x 2 meter) with CGI animation, which we created on the basis of secret historical drawings of the Flak tower.
