Zwingli-Hochbunker, Military bunker in Walle Bremen, Germany
The Zwingli-Hochbunker stands as a massive concrete structure with thick walls, designed to protect civilians during aerial bombardments in World War II.
During the heaviest air raid on Bremen in August 1944, this bunker provided shelter to 2000 people while fire rescue teams worked through extreme heat conditions.
The structure was named after Swiss reformer Ulrich Zwingli and represents a transformation from military defense to modern technology applications in Bremen's urban landscape.
The former military shelter now functions as a data center, utilizing geothermal energy systems installed in 2013 for sustainable power supply.
Between 1967 and 1979, the bunker received extensive renovations including decontamination showers and air filtration systems for potential nuclear threats.
