The Green Bunker was originally built during World War II as an anti-aircraft structure designed to shield the population from bomb attacks. For decades, it served as an emergency shelter, material storage, and even a vaccination station during times of crisis, including the Cold War era. After the reunification of Germany, the bunker was revived and repurposed, transforming into a space for leisure, events, and urban greening.
Today, this concrete giant features over 4,700 trees and large shrubs, which are automatically irrigated with rainwater. This sustainable greening effort demonstrates how Hamburg is adapting historical sites for future urban needs, blending history with ecology. The tour’s guides share the construction background and the story of its builders, making the experience both educational and inspiring.

Reaching the bunker involves climbing via a mountain path, which adds an element of physical activity to the tour. The ascent is not barrier-free, so visitors should be prepared for a moderate climb. The path offers close-up views of the building’s gray concrete exterior and sets the scene for the stories of those who built and used it during wartime.
Once at the top, visitors are greeted with access to the roof garden, where the panoramic views stretch across Hamburg. Here, you see sights like the Millerntor Stadium, Elbe Philharmonic Hall, Köhlbrand Bridge, and Harbor Container Port. This vantage point highlights Hamburg’s urban landscape and underscores the contrast between the bunker’s military past and the city’s modern development.

The tour is led by well-trained, friendly guides who bring the history to life through anecdotes and detailed explanations. They inform visitors about the construction techniques, wartime Waffentechnik (weapon technology), and the lives of Hamburg residents during the war. The guides also explain the sustainable greening concept and how the bunker began its third life as a community space.
According to a highly positive review, Guide Axel is praised for his humor, extensive knowledge, and engaging storytelling. Visitors appreciate the balanced mix of historical facts and entertaining commentary, which keeps the tour lively and informative without feeling rushed.
