World War II relics find new life: German flak towers repurposed across Europe. Berlin, Hamburg, and Vienna are among the cities where these massive structures, originally designed as anti-aircraft defenses, now serve as parks, rock climbing walls, and even an aquarium. "A lot of them are in parks, which is just fun," says WHAT HISTORY!, a history enthusiast who documented these repurposed towers in a recent video. The video shows how these imposing symbols of the past have been reimagined for peaceful use, highlighting the resilience of cities and the enduring legacy of World War II.
