Wartime graffiti on a prison cell door in the EL-DE Haus in Cologne, Germany.
Officially known as the NS Documentation Center of the City of Cologne, the EL-DE Haus was used by the Nazis from 1934 as the headquarters of its secret police, the Gestapo.
Surprisingly, the building survived the Allied bombing of Cologne during World War II, despite the fact that 90% of the city was smashed.
You can visit the building’s basement rooms that were used as prison cells and torture chambers, and its heartbreaking to see scrawls on the walls from people whose lives were destroyed by the Nazi regime.
