The Oberbaumbrücke, which links Kreuzberg to Friedrichshain, once marked the border between the East and West. Restored in the 1990s, its turrets, gables and crenellated arcades are typical of the Middle Ages and its neo-Gothic style (1896) is reminiscent of Tower Bridge in London. The bridge takes its name from the toll dyke made from tree trunks (Baum) which stood on this spot in the 18C.
