Hellersdorf is a Berlin U-Bahn station located on the line.
The station opened in July 1989, just a few months before the fall of the Berlin Wall. The eastern extension of line U5 was one of the last major construction projects of the former German Democratic Republic.
The station was to be called "Kastanienallee" but was changed to the current name before opening.
