Marzahn is a neighborhood in the Marzahn-Hellersdorf borough of Berlin, Germany. Known as Morczane during the Middle Ages, Marzahn became part of Greater Berlin in 1920 and was the site of a labor camp where Romanies were interned during the 1936 Summer Olympics. 2,000 Romani inmates were held at the camp until 1943, when they were deported to the Auschwitz concentration camp, where most of them were gassed. On 21 April 1945, Marzahn was the first of Berlin's boroughs to fall to the Soviet Red Army during the Battle of Berlin. Marzahn remained a rural district until 1977, when the East German government built housing estates on its fields. After the fall of the Berlin Wall in 1989, Marzahn became a hub of neo-Nazism, and foreigners were warned not to visit the area, even as significant Russian and Vietnamese communities developed there. In 2020, Marzahn had a population of 111,508 people.
