It was then called Kaiserhof after the nearby grand hotel on the Wilhelmplatz square, was designated by black and white at platform level, and had an oval opening to the stairs and a booking hall with elaborate tilework at the Wilhelmstraße end.
This entrance was rebuilt in 1936, the year of the Berlin Olympics, to provide more space for parades at the adjacent Reich Chancellery.
[3] The rebuilt station, now located in East Berlin, reopened on 18 August 1950 as Thälmannplatz, to which the Wilhelmplatz square had been renamed for the communist leader Ernst Thälmann.
Beginning in 1986 the square was overbuilt[2] by a housing estate and the Czechoslovakian Embassy, and on 15 April 1986 the station was renamed Otto-Grotewohl-Straße, the name of Wilhelmstraße at that time, after the politician Otto Grotewohl.
[6] The murder of George Floyd prompted anti-racist demonstrations and accompanying debates about structural racism in Germany; in response to this, the Berliner Verkehrsbetriebe (BVG) announced on 3 July 2020 that they would change the station name from Mohrenstraße to Glinkastraße,[7] after the street name at the station's eastern entrance, which honors the 19th-century Russian composer Mikhail Ivanovich Glinka.
