The factory was originally built by the Dynamit-Aktien-Gesellschaft (DAG) in the early 1940s.
At its peak, the site employed thousands of forced laborers, including Poles, Soviets, and prisoners from Stutthof concentration camp.
The buildings were constructed using distinct blast-resistant architecture, including thick concrete walls and reinforced roofs.
The site spans a huge forested area with dozens of production buildings, many of which remain overgrown or inaccessible.
The museum uses subterranean corridors to connect separate thematic exhibition halls.
It was one of the largest armaments factories in Nazi Germany during the Second World War.
The location was chosen for its dense forest cover, which helped camouflage the facility from Allied air reconnaissance.
The factory was captured by the Red Army in 1945 and partially dismantled before being abandoned for decades.
The Exploseum is an industrial museum situated within the preserved remains of the DAG Fabrik Bromberg, a massive Nazi German explosives factory built during WWII. The facility comprises several concrete, explosion-proof buildings connected by a network of underground tunnels. Exhibits focus on the history of the factory, the exploitation of forced laborers, and the chemistry of explosives. Visitors walk through converted production halls that retain their original architectural layout. The site covers approximately 20 hectares of the Bydgoszcz forest, highlighting the scale of the former armaments complex. Interactive displays detail the lives of the prisoners who worked in these hazardous conditions under the Third Reich. It serves as both a technical museum and a memorial to the victims of forced labor.
The long, narrow, illuminated concrete tunnel corridors that connect the various production halls.
Wear comfortable, sturdy walking shoes as the site involves significant walking over uneven paths between buildings.
Bring a light jacket even in summer, as the underground tunnels and concrete bunkers remain cool.
Allow extra time for exploring the forest paths between the main exhibition buildings.
Do not attempt to enter unmarked or fenced-off ruins in the surrounding forest, as these are structurally unstable.
Closed on Mondays.
Maintain a respectful tone due to the site's history as a forced labor camp; do not stray from marked paths in the forest.
