Renaming of Karl-Marx-Allee
West of the original site of Frankfurter Tor (now the junction with Straße der Pariser Kommune), Karl-Marx-Allee was called Große Frankfurter Straße and Frankfurter Allee to the east of that.
On 21 December 1949, the two streets were renamed Stalinallee to commemorate the celebrations of Joseph Stalin’s 70th birthday. Since 13 November 1961, the street has been called Karl-Marx-Allee between Alexanderplatz and the present-day Frankfurter Tor. The section to the east of Frankfurter Tor has been called Frankfurter Allee again since 1961.
