The red highlighted tour includes buildings used for the production of nitroglycerine. Nitroglycerine is a highly unstable liquid with strong explosive properties. The tour includes 7 buildings from the 2nd production line. This zone was put into operation in 1943. This area is ~ 0.5% of the total area of the DAG Fabrik Bromberg plant. The tour should take you around 2 hours to complete. You will receive an RFID card to navigate the route. The card only allows you to follow the direction of the tour - you will not be able to go backwards. The card must be returned at the last exhibition hall. Toilets are located in the main building (the building you are currently in) and at the end of the tour in Building 1157.
