Helmstedt–Marienborn border crossing

The Helmstedt-Marienborn crossing is a border museum in Sommersdorf with preserved control buildings, tunnels, and inspection facilities from the period of German division. The site spreads across a large area and shows the complex infrastructure that was needed to control border traffic.

The border checkpoint was established in 1945 and served until 1990 as the main control point between East and West Germany. It was a crucial crossing point on the main route to West Berlin and symbolized the country's political division during the Cold War.

The exhibitions in former control buildings show how people experienced the border and the feelings it provoked in daily life. Visitors can see how the border system functioned and what role this checkpoint played in Germany's division.

The site is open daily to visitors and offers guided tours in multiple languages that explain how the checkpoint operated. It is worth planning enough time to explore the buildings and exhibitions thoroughly.

The site featured a sophisticated tunnel system used for military transport and surveillance operations. This underground network illustrates the military dimension of the border facility.
