EL-DE Haus
The basics
Formerly the business of jeweller Leopold Dahmen, the EL-DE Haus (which takes its name from his initials) became one of Cologne’s most notorious and feared addresses during WWII. Its basement was used to host a prison and torture chambers; despite heavy bombing campaigns, it survived the city’s many air raids. Today, it’s home to the NS-Documentation Center, an award-winning museum that has been housed in the building since 1988. It memorializes Nazi victims across wide-ranging exhibitions and is a major research center.
Things to know before you go
- Audio guides, available for a small fee in eight languages, offer an accessible way to explore the museum’s permanent exhibition.
- The building’s basement prison is now a moving memorial site to Nazi victims; the cells feature over 1,300 inscriptions and drawings on the walls, which have been preserved.
- Temporary exhibitions are held as a supplement to the permanent collection, and address local and national perspectives on the Nazi era.
- Free admission is granted to children aged 0–6; free entry is also offered on the first Thursday of every month.
- Free guided tours are offered once per month; it’s also possible to pre-book guided tours in English, French, Italian, Polish and Spanish.
- Unfortunately, due to its heritage architecture, the EL-DE Haus is not accessible to wheelchair users.
