Between border installations and remembrance culture

The border installations at Lake Jungfernsee were used until 1990 for processing cross-border traffic on the waterways of the GDR. Key relics of the former control point have remained, which today serve as a memorial to division, the Cold War, and the victims of the border. It is this connection of historical significance and original substance that shapes the unique atmosphere for visitors on site.
