Hellersdorf is a locality in the borough of Marzahn-Hellersdorf in Berlin. Between 1986 and Berlin's 2001 administrative reform, it was a borough in its own right, consisting of the current area of Hellersdorf as well as Kaulsdorf and Mahlsdorf.
Before German reunification in 1989 it was part of East Berlin. Situated at the eastern rim of Berlin, the area is mainly a large housing estate from the 1980s, made up of Plattenbau (concrete slab) buildings.
The historic village of Helwichstorpp was first mentioned in a 1375 land registry of Emperor Charles IV of Luxembourg, then also Margrave of Brandenburg. The city of Berlin acquired the former Hellersdorf manor in 1886; it was finally incorporated by the 1920 Greater Berlin Act as a part of the Lichtenberg borough. During German reunification on October 3, 1990, a small part of Honow (primarily around the last two stations of U5) was annexed by this borough.
Hellersdorf is divided into 3 zones (Ortslagen):
Hellersdorf is served by the U5 line of the Berlin U-Bahn at the stations Kaulsdorf-Nord, Neue Grottkauer Straße, Cottbusser Platz, Hellersdorf, Louis-Lewin-Straße and Hönow.
