NS Documentation Center, Cologne (must see)
In the heart of Cologne stands a building once marked by silence, now filled with testimony—the NS Documentation Center, housed in the former headquarters of the Cologne Gestapo. From 1935 to 1945, this unassuming structure served as a key site of Nazi terror. Known as the EL-DE Haus—a name derived from the initials of businessman Leopold Dahmen, who leased the still-unfinished building to the Nazis—it became a dark chapter in the city’s history.
Beneath its ground floor, ten prison cells were constructed in the basement. Today, that space endures as one of the most chilling and best-preserved Nazi detention sites in Germany. The Gestapo Prison memorial is now the country’s largest memorial dedicated to victims of Nazi persecution. More than 1,800 inscriptions—carved or written on the cell walls by prisoners—remain, bearing raw witness to suffering, hope, despair, and resistance.
The permanent exhibition above examines the rise and machinery of National Socialism, with a particular focus on Cologne’s experience under the regime. Visitors will encounter detailed accounts of Nazi propaganda, administrative structures, systemic racism, and the deportation and murder of the city’s Jewish population. Stories of local resistance movements also find their place here—quiet acts of defiance that stood against overwhelming force.
The Center functions not only as a museum but as a research institution. Its library and archives continue to support scholarship on the Nazi era, ensuring that this part of history remains rigorously studied and publicly accessible.
A word to visitors:
Take the audio guide—it’s essential for grasping the deeper context behind what you’ll see. Start your journey in the basement, among the cells, and work your way upward. Lockers are available free of charge to store bags, leaving you free to absorb the weight of this place with undivided attention.

Cologne's Architectural Landmarks Walking Tour
Around 75% of Cologne was destroyed by Allied bombing during World War II. Following such devastation, it meant that most of what was built immediately after the war came from the so-called “As quickly and cheaply as possible” school of architecture. Eventually, as the things settled, the architects were given the chance to build something that would really stand out.
