Was Hamburg ever directly targeted during WWII? The answer lies within the story of the St. Pauli Bunker, also known as Flakturm IV. It is a stark reminder of a tumultuous past. This massive structure dominates the St. Pauli skyline. It offers a glimpse into Hamburg’s wartime experience.
In 1940, in response to Allied Forces air-raids on Berlin, the Nazi regime ordered air-raid shelters to be built across the Third Reich. Hamburg, a vital location for U-Boot and oil industries, was a prime target. By the end of WWII, Hamburg had 1,051 bunkers. That’s more than any other German city. Today, about 650 bunkers remain.
The St. Pauli Bunker was one of the largest. In 1942, one thousand forced laborers built it. The bunker measured 75 by 75 meters in width. It stood 35 meters tall. Its walls were 3.5 meters thick. It was designed to hold 18,000 people. There was a special extra-wide entrance for women. They had prams and children. During the air raids in 1943, 25,000 people sought shelter here. The bunker’s thick walls protected them. Allied forces neutralized the bunker’s missile firing capabilities. They released tin foil strips. These strips interfered with the bunker’s radios.
After the war, plans to demolish the bunker were dismissed. Too much explosive would be required. It would likely damage surrounding residential areas. Since then, the bunker has served various civil purposes. In 1950, the public broadcaster NWDR broadcast the first television images in Germany from this very site.
Today, the St. Pauli Bunker has been repurposed. Its impenetrable walls make it perfect for loud events. Uebel&Gefährlich nightclub is on the top floor. It is a popular spot for live and electronic music. The ground floor houses a large climbing hall for bouldering. The Resonanzraum provides space for jazz and experimental music. A pop music school, artists, actors and musicians have offices here.
In July 2024, the roof of the bunker opened to the public. It is now home to a five-story hotel. There is also a restaurant complex with a sports and concert hall and exhibition spaces. Lush greenery is visible from afar. The top of the bunker hotel boasts a public garden. It offers stunning views of the city and port. The green roof and facade cool down temperatures in St. Pauli. They also provide shelter for birds and insects. The St. Pauli Bunker stands. It is not only a reminder of history but also a symbol of Hamburg’s resilience. It represents its ability to adapt and transform.
