The Bunker

We learned some of the following about this historical site:

The St. Pauli Green Bunker (Flak Tower IV)
History and Transformation. Original Structure: Massive WWII Flak Tower IV (Flakturm IV). Built in 1942, reportedly in less than 300 days, using forced labour. Served as an air raid shelter for up to 25,000 people. Still stands as an indestructible-looking concrete fortress; now a memorial to the victims of the Nazi regime and WWII.

The Green Transformation: A 5-story extension added to the top of the bunker to create the "Green Bunker." The project focuses on sustainability and urban ecology. The entire exterior of the extension is covered in greenery (thousands of plants, shrubs, and trees).

Access/Movement: The "Mountain Path" (Bergpfad) is the key feature for reaching the top. It’s a 560-meter-long circular outdoor ramp/staircase winding up the side. The views change as you ascend. (There’s also an elevator.)
Current Usage & Culture

Rooftop Garden: The top level is a beautiful, free, public green oasis with panoramic views, open daily. The bunker is a vibrant cultural hub. Home to a famous nightclub (Uebel&Gefährlich), a climbing hall, studios, and event spaces like the Georg-Elser-Halle.

Hospitality: Includes a hotel (like REVERB by Hard Rock Hamburg), and restaurants/bars (like La Sala and KARO&PAUL).
Key Views from the Top
The 360-degree view gives a clear perspective on several major Hamburg landmarks: The Millerntor-Stadion (FC St. Pauli’s home) and the massive Heiligengeistfeld event grounds (where the Hamburger Dom funfair is held). My photo of the stadium was taken from here. The Port of Hamburg and the cranes in the distance. The striking glass of the Elbphilharmonie concert hall. The spire of St. Michael's Church (Der Michel).

Excellent view over the adjacent St. Pauli, Reeperbahn (nightlife), and the creative Karolinenviertel districts.
