Moltke Bridge

Today's massive bridge has two predecessors. A wooden swing bridge known as the Unterspree Bridge had stood about 70 meters upstream since 1851. It was designed in order to be able to run the connecting railway between the Hamburger Bahnhof and the Potsdamer Bahnhof over the Spree. Because the wooden structure quickly became dilapidated, the first wrought-iron triple-arch truss bridge in Germany was erected in 1864–1865 south of it. The Moltke Bridge was built in its place. Due to the bad experience with the metal construction of the second Unterspreebrücke it was built as a solid structure. Work on it began as early as 1886, before the previous building was demolished, and continued until 1891. During the Second World War, the Moltke bridge was badly affected. In 1942, bronze decorative elements from the bridge and the lanterns attached to it were removed and melted down for armaments purposes. In the final days of the Battle of Berlin, the bridge gained strategic importance when units from the Red Army led the attack on the Reichstag building from Moabit. There were fierce fights in the course of which the southern arch of the bridge was blown up and parapets and sculptures were badly damaged.
