Hochbunker Humboldtstraße

This massive reinforced concrete structure features exterior walls measuring 43 inches (1.1 meters) thick and rises up to seven stories tall, designed with minimal decorative elements that emphasize its functional military purpose during wartime.

The bunker was constructed during World War II as part of Hamburg's extensive network of approximately 700 air raid shelters built to protect civilians from Allied bombing campaigns over the city.

After serving as rehearsal space for local musicians and bands organized by RockBüro e.V. until 2008, the building represents Hamburg's ongoing effort to repurpose military structures for peaceful community uses.

The structure is located at Humboldtstraße 91 through 99 in the Hamburg-Nord borough, postal code 22083, and can be reached in the residential neighborhood of Barmbek-Süd within the city.

In 2012, developers added two maisonette-style apartments on the roof of the bunker, transforming the former military shelter into modern residential housing while preserving the original concrete structure below.
