Hochbunker Körnerstraße, Air-raid shelter in Ehrenfeld, Cologne, Germany.

Hochbunker Körnerstraße is a freestanding, three-story reinforced-concrete shelter measuring 50.3 by 15 metres, its long side parallel to the street, with a hipped roof of pan tiles. The roof slab and floor are 1.4 metres thick, basement walls 1.8 metres, upper-floor walls 1.1 metres. Its facade is split into a pale yellow and a grey painted section, with a banner reading "Ehrenfeld gegen Gewalt und Rassismus".

Built in 1943 during intense bombing campaigns against Cologne, this shelter was designed to protect large numbers of residents. After the war ended, it was repurposed and eventually protected as a historical monument.

The building is known as bunker k101 and serves as a place of culture and remembrance. The white banner reading "Ehrenfeld gegen Gewalt und Rassismus" recalls a 1989 response by the Cologne youth ring to right-wing slogans painted on the bunker. In 1991, 90 children's drawings from the Theresienstadt ghetto were exhibited here.

The bunker stands between house numbers 91 and 113 on Körnerstraße, its long side running parallel to the street. It has been a listed monument since 25 April 1995. The building is used today as bunker k101 for culture and remembrance, so access depends on the events held there rather than on regular opening hours.

The shelter stands just steps away from where the Körnerstraße Synagogue once stood before its destruction during the Nazi pogroms. This proximity connects two parts of the same tragic history in one neighborhood.
