From the same corner, Karl-Liebknecht-Straße runs northeast alongside the square and on to Alexanderplatz.

Other cities which have a Schloßplatz include Frankfurt am Main, Stuttgart, Munich and Dresden.

The Council of State building contains a balcony from the former city palace, where Karl Liebknecht proclaimed a socialist republic on November 9, 1918.

It houses a conference centre and several museum collections of the Humboldt Forum, which opened online on 16 December 2020.

The music video for the song 'Ich Will' (I Want) by the German band Rammstein was filmed in this location.
